One of the few installs where I dont see a raceway under the 15k, looks better without the big raceway IMO. Seems like almost all professional installers use them though... Any reason for going this route?
This system replaced an old 24V Outback system at a clients home. We rewired the solar modules from strings of 1 to strings of 6 and added this power station which can be expanded in any way they need.
I would never install a high frequency, transfotmerless inverter in my off grid home. Transformerless, high frequency inverters offer a substantially lower surge capacity, a shorter life expectancy and run much hotter than heavy duty, low frequency, transformer based inverters. And their fans are louder because they run hotter.
The majority of what you said USED to be true. Luxpower (manufacturer of EG4 inverters) has HF inverters that have generated over 100MWh (yes, 100,000kWh) of energy which are still operating optimally to this day. Surge capabilities and life span have dramatically increased in the last few years as well. Hence warranty period increases. Many inverters are still lousy with fan noise, I admit. LF inverters are still great for heavy inductive loads, but they are no longer the end all be all they used to be. Especially for the typical homeowner who only has one AC unit to contend with. No problem for more than one if they have inverter driven AC units or soft starts at the very least. Put two or three inexpensive HF 240V stand alone inverters on the wall sharing the loads and they can last a very long time generating a large amount of energy. This also gives you redundancy in case one fails till you can replace it which will be fast since most are AIO's now days. No reason to keep bashing systems that are now proven with many years of service like Sol-Ark, just makes you look bitter.
I have had two HF inverters on my wall for 4 years now. They have produced many kilowatthours of energy and are still going strong. They have already paid for themselves at least twice. No problems running my 4-ton AC either.
Two high frequency inverters in what sort of application? Grid Tie, off grid, emergency battery backup? What brand and what kW rating? Thanks.@@hicapengrs
What I said still hold true today. High frequency, transformerless inverter offer a shorter life expectancy and they offer a lower surge capacity, when compare to low frequency, transformer based inverters. Both EG4 and the Sol-Ark have not been on the market long enough to prove their longevity. Signature Solar, importers of the EG4 inverter has only been in business for approximately 3 years and Portable Power LLC, the alleged manufacturers of the Solar-Ark line of inverters has only been in business for 7 years. Both relative newbies to the inverter industry when compared to major inverter manufacturers like Schneider Electric, Outback Power and Magnum Energy to name a few. I've been in this industry repairing both transformerless and transformer based inverters for the past 24 years and based on that experience, I can confirm that little has changed in the design of high frequency, transformerless inverters. I can also tell you that a mere 200% surge capacity is hardly an improvement from these inverter's original surge rating design, especially when you consider that most inductive loads require at least a 300% to 800% surge capability. Oh, and I'm not bashing anyone's product. I'm just educating the public on the true capabilities of these products. Besides, why would I intentionally bash anyone's high frequency inverter product? After all, the more of these light duty, high frequency inverters that are sold, and fail after a few years of use, the more customer's my inverter repair center acquires. @@URackADisciprine
Your setup looks really clean and tidy. Great job.
Thank you!

Is this your business or residence? It sounds like an industrial plant!

Price 30000. Six panels will not charge that battery full
This system has 18 modules and charges the battery full in less than half of the day.
