This is a huge sale on a fantastic product

Went on sale only Wednesday this week - no idea how long it will last

But this is one of the best AIO Inverters in the market with a great level of power available

Clearly it needs to be linked with batteries and Solar Panels

But a great price

I installed an EG4 18KPV inverter and EG4 battery rack system about a year ago. It's not perfect, but for what I paid I am extremely happy with it.

My biggest gripe with the system is the UI for programming/controlling the inverter is not very well designed and fairly buggy. The menus/settings between the unit/app/web based UI are all different and have conflicting settings that don't always transfer. I ended up getting it all set up right eventually through trial and error, and luckily once it's set up you don't need to touch it again, but it was a bit of a pita.

I think they call this a hybrid inverter, not an aio. Aoi have battery built in.

Says it's an off-grid inverter, but the spec sheet says it implements UL1741 (anti-islanding). Doesn't say anything about implementing other specs like HECO or CA requirements. Round-trip efficiency is only about 83%. Split phase is good. Cheaper ones require two separate inverters to get 240V split-phase, which is what's generally wired to homes in the US.
