I assume that you will be installing a battery backed system to store daytime energy for evening use? I don't know anything about SolArk inverters. But I have SMA battery backed system and Solar Edge Energy Hub system installed in my lab. Both have a 10 kWh LG battery. We have only have them each for few months so can't say alot about performance. The SMA is AC coupled meaning you have 2 inverters, one is PV inverter (sunny boy or SB model) and other is battery charging (sunny boy storage or SBS model). It requires an advanced battery unit (ABU) transfer switch and grid interaction unit. My installer says the SMA SB inverters are great but the ABU and SBS are not so reliable. The customer interface for SB called Sunny Explorer or Sunny Portal are great, providing detailed control of operating parameters and feedback. You will need them to control the battery charging characteristic. SMA customer service is helpful and responsive.The Solar Edge Energy Hub is DC coupled so only one small inverter/charger. It also integrates the outdoor sensors (sunlight, temperature) and the EV charger. Designed to be used with module power optimizers Also has a very helpful and intuitive customer interface portal. It is designed as to be a residential microgrid. I have not had enough experience to evaluate the performance over time.Steve
I would talk to Scott Hunt at Practical Preppers. He has a lot of experience with Sol Ark and from what I have seen they made some nice technical advancements over the last few years. I currently have a grid tied PV array that uses micro inverters but I think I would probably seriously consider using Sol Ark if I were just starting out with a PV system.
