    Very good. I have been doing some research and the eg4 3kw looked good for what I needed but the documentation leaves a lot to be desired. I just wanted to see someone else do it and explain their thoughts. We seem to be on the same wavelength. I appreciate your video!

      I’m uploading a video of connecting 4 EG4 3000 watt inverters in parallel but taking forever. I was only running 2 with a load so I was maxed out at 6000 watts using a small electrical panel with 2-30 amp breakers and 2-15 amp breakers. I could not use all I was producing so I retired to my large electrical panel for 200 amp service. I still need to connect a total of 16,000 to 20,000 total watts in solar panels to the inverters. 4000-5000 watts on each inverter with a 35.5kwh EG4 LiFePO4 battery bank. I just connected and tested the system with 4000 watts in new solar panels and 2000 watts of used 250 watt poly solar panels on 2nd inverter, 4000 watts used 250 watt poly solar panels on 3rd inverter and 4000 watts of used poly solar panels on 4th inverter. I was able to start my 3 1/2 ton then a minute later started my 4 ton ac as well, so I had both 3 1/2 ton and 4 ton ac running at the same time. I was using around 6500 watts and discharging my battery bank.3 amps. So I still need to reconfigure my solar arrays to have 5000 watts on all 4 arrays, then I think I will be able to run 10,000 watts to 12,000 watts output. I am ordering more bifacial solar panels soon but just wanted to let you know 4 inverters in parallel have no problem starting and running the large loads I was running on my 12kw Growatt low frequency inverters. These weigh 18 lbs, the Growatt weighs 186 lbs. these little power house EG4 inverters are a major game changer!!!! I run my 3 1/2 ton ac overnight on my 25.5 kWh battery bank and have over 50 percent state of charge left at 7am. I going to use one of these in my motor home to run a 120 volt 12,000 btu mini split that cools it down insanely fast compared to rooftop ac that is now very efficient. Look for my next video if it ever gets uploaded to RUclips sometime soon. It is all about the EG4 3000 watt inverters in parallel. I think you will like the info I give in video. Thanks for your comment and I hope you have a truly wonderful and extremely blessed day.

Weighing only 18 is insane for the power you get out of this unit.

      @diysolaradventures7894 for now I am bonding in my electrical solar panels. I also when adding 120 volt electric outlets, ground the outlet wires to the ground on inverter. If I lived completely off grid in the middle of no where where there is not electricity available I would definitely earth ground over bonding to electrical panel. But since they cram these houses so close together, I pick up voltage in ground no matter where I try to ground in my yard. When I did earth ground at first I was having a lot of problems with tripping gfi outlets and getting shocks from the metal wire racks the batteries were on even though there was no metal to metal contact. I was getting a shock. When bonding, you can also get a shock as well but I noticed a big difference in how little the shock was when binding to electrical solar off grid breaker panel. So all my inverters are now bonded to solar off grid breaker panels and I feel comfortable with that. Hope this helps.

    • @diy-solar-guy
      @diy-solar-guy  6 месяцев назад +1

      These are 3 separate independent systems I am running. I bought the 12kw Growatt refurbished at a great price and when they had free freight. But the 12kw Growatt are not able to parallel but I can connect a EG4 charge controller to the bus bar and supplement the loads to run a 12.7 ton pool heater heat pump. I am using 12,000 watts of used solar panels and can only get 6500 watts output on each 12kw Growatt inverter. I produce far more than I can use but all the equipment is paid for through the savings on my electric bill. It’s free electricity at this point. Now the EG4 3000 watt inverter can be paralleled up to 12 units with each unit surging 50 amps for 5 seconds. That is a big deal when trying to start large loads. I am in the process of uploading a video of what can be done will these 2 EG4 3000 watt inverters in parallel. I think most will be very surprised at the ability of these 18lb inverters. These are not low frequency inverters like the Growatt 12kw inverters. Check out my video I will post in a few days and see why I got the 2-3000 watt EG4 inverters. In the meantime, check out my other videos on bifacial solar panels and on everything we are able to run with our off grid solar power system.

Just take your time and figure out what you want to run and when picking components, think about being able to expand your system where you can add more solar panels and more inverters in parallel. These EG4 3000 watt inverters are great, you can expand up to 12 inverters in parallel to create 36,000 watts output. That is a huge amount of power. I am in the middle of connecting 4-EG4 inverters in parallel to get 12,000 watts output. My Growatt inverters barely put out half of that. Those EG4 batteries are also great for overnight use, I just received another 2-EG4 51.2 volt 100 ah 5120wh version 2 ULlisted server rack batteries. I will now have a total of 46kwh of server rack batteries to run my ac, pool pump, freezers, fridge, light, etc… overnight every night.

    Why do you have the perspective that the dual EG4’s can not start your 3-1/2 ton or 4 ton AC if you have a soft start on them? My 4 ton heat pump with a soft start is only pulling about 2500 watts (with the blower) on 1st stage and only about 3000 watts on the 2nd stage. I have an Emporia Vue CT on the AC and don’t see any big surge on amps at startup. Given the EG4’s can handle about twice the wattage for 5 seconds, it should not trip them. I only have one 3k inverter so I can not try it out on my AC.

    • @diy-solar-guy
      @diy-solar-guy  6 месяцев назад

      The surge on the EG4 will not start the 3 1/2 ton according to the reps at signature solar even with a soft start. I have 2 - 12kw Growatt off grid low frequency inverters. They are independent systems, not in parallel and those are the only inverters that have been able to start 3 1/2 ton. These high frequency do not have a large coil in them like the low frequency inverters and just can’t take the surge. I tried 6 different high frequency and they are no good for starting up 3 1/2 ton heat pump. These high frequency are not designed to handle that large of a surge even with a soft start. Let me know if you find anyone out there able to start a 3 1/2 ton heat pump with a high frequency inverter. The inrush amps on my 3 1/2 ton before soft start was around 78 amps, after soft start, it is around 20-24 amps. 20 amp at 230 volts is around 4600 watts. I don’t need to try with these EG4 3000 watt inverters, I know enough through actual experience that they are just not designed to start up that load , in fact the 6000 watt EG4 can’t start it as well but the 12,000 EG4 that can have 18,000 watts connected is suppose to be able to start up a 3 1/2 ton ac. That 12 kw EG4 is over $5000 and my growatt 12kw is half the price and can start 3 1/2 ton and then the 4 ton heat pump and run both at the same time. Hope this helps. You need that low frequency inverter with big coil to start 3 1/2 ton. That 12 kw Growatt inverter weighs 186 lbs because if that coil inside. A beast to mount on wall.

Solar input when cloudy or raining can drop significantly to where you might only have 20 percent input or less. In Arizona, we have over 320 days of full sunshine and very little rain, especially in Phoenix because of the heat island effect from very little trees or grass and mostly buildings, roads, houses and vehicles adding to heat keeping the clouds from being over the whole Phoenix area.

      The two in parallel to run a 230 load overnight will use around 50 watts each inverter at idle consumption. I run my 3 1/2 ton upstairs heat pump to air condition overnight and find these two together are only half of what the 12kw Growatt use to use overnight. During the day when I have sun is from 7 am to 7pm, during this time the solar input covers the 100 watt idle consumption so it is only 1200 watts overnight when there is no sun. That is only 1.2 kWh of battery so I can run my 3 1/2 ton ac on battery bank overnight. I don’t think you will find anything less idle consumption to be able to handle the inrush from ac. Eviction is good but not for starting 3 1/2 ton heat pumps. Could be used to run 12,000 Btu mini split overnight if you have a eviction that can handle at least 1500 watts continuously

      Thanks for your input. We appreciate it. System runs flawlessly. I have 3 separate independent off grid system in a small area and it is a lot of wires. All the wires stay cool to the touch and we keep our garage around 62-65 degrees while running inverters during the day from 7am-7pm. I need to replace my used solar panels with new bifacial solar panels . On your home for the grid all the wires from electrical distribution panel are behind the wall but on an off grid system that you want to be able to take with down the road if you ever sell and move, your wiring is outside the wall. Everything you want to run has to have a separate wire running to it. I have 3 separate independent electrical outlets that our in back yard up to 100 feet away from inverter. Then I have separate wires that run to a3 1/2 ton, 4 ton heat pump, a 12.7 ton pool heater, a 1 1/2 ton pool heater a 2-1 ton mini splits as well as my pool heat pump. Then there are 2 mini splits up stairs and 2 mini splits down stairs as well as the 18,000 btu mini split in the garage. If I move to a house completely off grid, I have enough to supply entire house. But when you set up off grid, you have a lot of wires. Connecting to grid is very few wires but they charge you a lot more here to connect to the grid. If I supplied 100 percent of me electric and did not use any grid power, my bill would still be almost $2,000 a year. And the bill keeps going up every year for using the same amount of electricity. You have to e to decide how to manage your wires according to your situation and how much you want to run. Making it work and making it look pretty are to different things. I’m not trying to look pretty in video, I’m trying to show how to use off grid and what you can run with it. I plan on moving down the road and will take off grid system with me and have made the least amount of holes in the wall so I can restore wall back to original shape when removing entire system. We plan on moving to a smaller home that is half the size of current home. Thanks again for your input and hope you have a truly wonderful and extremely blessed 2024.

      @@Gary-ee3kq We now use double the electricity we use to. Before off grid solar, we set our thermostat at 83 degrees while at work and 80 degrees while at home, 78 while sleeping. Now the house upstairs is around 72-76 degrees in summer and down stairs overnight is around 78-80 degrees. We run our pool pump 24 hours a day with no problems with water, no algae or cloudy water. We run 4 freezer and a refrigerator 24 hours a day. We also have our garage air conditioned, usually 75 degrees in garage during the day when 100-117 degrees outside during the day. Our electric bill in Phoenix ax area is less than $200 a month in the summer while my neighbor will spend $600-$1000 a month with a 2 story house and a swimming pool. Our pay back time is very short since our electric bill with what we use now would be over $5000 a year. We spend around $1200 a year on electricity. We produce a lot more than we can use. We started off small and just built on it over last 4 years. We also use our electric pool heaters to heat or cool our swimming pool to 86-89 degrees. This is a diy investment. If you can do all the work yourself, your payback time is much shorter. With the savings on electric bill alone, we will be spending thousands less on electricity every year from here on out. Like I said, we use to be hot all the time before off grid solar, now we are very comfortable in the summer in house and garage. You could never get a payback time this short with on grid solar. We checked and our basic electricity bill would have been a minimum of $125 a months before we even used any electricity. We would never pay back our investment by going on grid solar. Hope this helps you understand better on return of investment. Electricity rates keep increasing, California is $.34 a kWh. Phoenix is $.17 a kWh. Hope you are blessed weather you do nothing or at least try to use off grid solar to offset electric bill. I know when we just used solar in the day to air condition the house and grid power at night, we reduced our electric usage by over 50 percent. We run our ac out here from March until as late as December. It’s hot in the day out here most of the year. We also have around 320 sunny day a year. Hope you have a blessed 2024

      Your energy costs is higher than I expected. I thought it was going to be very close to your northern neighbors in NV at 11-12c. On grid solar is a ripoff unless you DIY. My neighbors paid $35k for a 6kw Sun Run system with micro inverters. Even with energy costs at 37c/kwh here in Nor Cal still going to take years to pay vs I paid $7k for 9kw system made up of 300w Hyundai panels (signature solar), (2) lv6548 inverters, and cheap eBay 12V 100ah lipo batts and connected directly to my house breaker box with AC bypass enabled for times I've no more juice in the batts. Central AC units are extremely inefficient, so I r20 all the outlets and inlets and installed a 18k btu mini split. Also no reason to run the pool pump 24/7 when 12/7 gives the same results.

      @Gary-ee3kq the only way to get fast pay back is to diy off grid. If I would have went on grid, my electric bill would have been 3 times what I pay now and I would have been paying for it first 20-25 years with no possibility of actually breaking even. That is why I went off grid diy. I use double of what I use to and can produce twice that as well. I love not having to worry about high electric bills
