I''m looking for an Inverter size, at least 18kw output or 20kw output, in California. Max usage is well over 16kw if everything turn on at once, so that I need a large inverter which
Its 3 MPPT inputs support up to 28,800W of PV input, with a high-efficiency rating of 97.6%, ensuring you capture and use as much solar power as possible. The Sol-Ark 18K-2P includes
The EG4 18kPV Inverter was considered to be EG4''s most powerful and user-friendly inverter—until the FlexBOSS 21 entered the scene. Even with its newer, flashier brother now

The 18kPV is a 48V split-phase hybrid inverter that’s capable of running off-grid, in grid-assist hybrid mode, or even as a grid-connected unit that allows you to sell power back to the grid for net metering purposes. Here’s a quick look at its specifications and features according to EG4:
The 18K 2P supports more PV than any other residential inverter (over 40kW when utilizing AC coupled functionality). This power-house unit runs American engineered firmware, keeps your data stateside, and comes standard with a 10 year warranty. Don’t rely on the grid, take control of your energy. Innovative. Simple. Secure.
Most 5kW inverters consume 50-70W of power when not in use. Victron and Schneider have the most efficient inverters, but this efficiency comes at a price. Some inverters have off switches with remote buttons or have software that detects a load and then switches on.
The combination of these two things means that it's probably not worth your while having a system at 6 kW. A 5 kW inverter will be the most cost effective. And the extra 1 kW of panels means that you'll get best use out of your inverter - it will spend more time running at its peak output.
If you have 10kW inverter, it’s because you will need to draw 10kW of power at some point and if there is loadshedding and no sun, the batteries should be able to provide for that 10kW draw.

Engineered for the most grueling off-grid or back-up needs, the 18K-2P delivers up to 18kW of continuous power directly from battery storage to support large loads and 36kVA of surge power for 10s to ensure demanding loads like HVAC units and motors have no problem starting in a grid-down scenario.
