Try Solar, the Grid will always take you back
-If you are getting an installer rate on solark/deye the EG4 unit has an installer cost structure too, not apples-to applesI don't wanna taint your interests, and I'm sure many people will argue with me when they see my post. Against my better judgment if you're considering Sol-Ark, look no further. Signature Solar and EG4 make great reliable batteries, it's probably the hottest-selling item for them. The 18K is a new product, it has bugs, some very significant for other members of the forum (look around for 18K woes). It will probably become a better product with firmware updates and maybe even a hardware revision in the future. In my experience the Sol-Ark line is more polished, the Support one can argue is better than what you'll get from Signature and it works perfectly with the EG4 batteries.
The best news is, recently in the last 60 days (ish) the price has come down on the Sol-Arks, my 15K was $5500 roughly the same as the 18K from EG4 and I would argue given the maturity, software stability, support, and large market of partnerships and compatibility, not to mention good documentation, it's simply a better choice for nearly the same price.
-the 18k will support the Eg4 batteries the best over time, it has tigo monitoring integration now (industry first for hybrid inverter) and total battery shutdown.
-over 1500 EG4 18k systems have been installed since may and it is our most successful inverter ever.
-the 15k has no line balancing when off grid and is 500v vs 600v Pv input for shorter strings.
-you have way more control of the 18kpv than the 15k remote
