    Ive been using my growatt 24v for some time now, absolutely love it. You can over panel the unit but make sure you set the solar charging amps to 70-73 not 80... any more than 2000 watts incoming into the unit will fry the mppt. Trust me

      Wow, interesting. After asking about over paneling on for the growatt es ( diysolarforum.com/threads/can-i-over-panel-a-growatt.58714/#post-730299 ) ... I felt pretty comfortable over paneling. Should I still be concerned?

      @DIY Solar Fun with Ray Loveless I would be, I over paneled my unit and between the charge and load it pulled over 2400w and it cooked the mppt. Had to order another unit. Once I went in and limited the charge amps to 72 It never goes over 2000w and just caps out all day. On a cloudy day it preforms very well as i have a 3s5p array using 250w panels.

    Great video. I run the 24v version in my house for critical loads. I feed it into a Reliant 6 circuit generator transfer switch for flexibility. I set the mode seasonally. Winter is UPS mode and summer is Solar priority. There is a Neutral/ Ground bonding issue with these units, and there are multiple NG bonds on the circuit board. This caused problems with several GFCI breakers in my main panel. There are several videos on this topic floating around.

      It sounds like I might have the same or similar set-up as you and am also having issues when plugged into a GFCI receptacle for AC In. In my case I am sending the AC Out back to the same panel as my AC in vis a Reliance manual transfer switch. My GFCI trips if I also have the AC Out connected, and is fine if I don't. It would seem like A neutral to ground bonding issue, and I have tried disconnecting ground from the GFCI, and that prevents the tripping, but only when AC is in standby. As soon as I switch it in to say charge my batteries - instant trip. How have you solved the problem on your end?

Also signature solar could help you set it up on the phone pretty easily if the setting isn't clear. It's pretty easy. If you don't need to connect solar I think I the 3000 es/ 5000es model instead. They're just a little bit newer and have a better interface.

    It seems growWatt and EG4 aren’t the best made inverters! I’ve been watching lately as people have struggled with these. I’m not sure if it’s the firmware or build quality or both!
    I’ve had two different Victron inverters, and I’ve never had any problems at all! The only issue I ever had was pre-charging the inverter in order to get it to work properly. But from what I hear, you have to do that on all of them.
    Let’s hope they get the bugs out ! 🖖

      @@diySolarPowerFunWithRay The ES version has a high start up voltage which means more panels and large panels which is not ideal for and RV. I would stick with the 145v version for RV use and get an ES version for home. Another advantage of the ES for home use is that you can run one large string of panels and not have to use super thick conductors for your panels.

    • @diySolarPowerFunWithRay

      ​@LeafNutz thanks. On my RV I will be using 6 40 volt, 315w panels in series. I have been doing a lot of testing and I think in most shade scenarios I still should be above the 120 operating V min limit for the es model. I also plan on having a combiner box where I can plug in 3 extra strings of 6 volt panels just in case an emergency and I need over paneling for shade situations. It would be similar to power traveling trailer.
      . But with my RV At least that is what I am envisioning it to be . Hopefully setting up the es version is not going to be a mistake.

      @@diySolarPowerFunWithRay Unless you can maintain over 160v, I would stick with the 145v NON ES version. I'm hoping you meant 6 400 watt panels and not 40 watt panels. The main advantage of the ES model's higher voltage is running single string with no combiner box. I run 6 365 watt panels in a single string for about 240v VOC and it works great. Just make sure you install a panel disconnect or DC breaker to shut off the panels anytime you need to swap stuff out.

      Yes, you can definitely do that. I am not sure if you can determine a specific cut off point.

Or use your utility first and always have battery available in Case utility goes out.

    If the Growatt is supplying the load (the powerstrip in this example, 6:36) by AC Power from the Grid, is it also simultaneously charging the battery if connected?

    • @diySolarPowerFunWithRay
      @diySolarPowerFunWithRay  Год назад +1

      The AC charger charges 120v at 40 amps. There is a setting that you can specify how much of those 40 amps you want dedicated to charging the battery. For example, Say it's dark outside(no-solar) and plug into shore power that can provide the full 40amp AC charging... if you specify 30 amps battery for battery charging.. You'll then have 10 amps to run your loads with. You can adjust the ratios for your needs. If you have solar that can also supplement power for you. I haven't messed with that setting much.. but that's my understanding... I mailed this unit in in-exchange for the "es" model so sorry I can't 100% confirm that for you.

    What gauge (AWG) wire are you using to connect the solar to the Growatt? It looks like 8AWG but I have found that most of the MC4 connectors are for 10AWG and smaller. My panels will be far from the Growatt and will need at least 8AWG and so need MC4 connectors that can accommodate the "large" wire.
