Waffled on inverters for a while when planning and buying the hardware to build my system, but its been running for 3 years now without a single issue. We run as off-grid, but with grid backup, zero export due to power company. We have 25.5kw of panels connected, and 51.2 kw of batteries. We run a 2400 sq ft house with 5 ton conventional A/C, a 1200 sq ft indoor shop with a 3 ton mr cool split, all electric appliances, and a 800 ft deep well with conventional Grundfos 240v well pump. We have grid outages all the time as we are super remote, however the system has never had a single overload or fault, runs the well just fine, the A/Cs, everything. Sol Ark is very good about making sure their systems can handle more than advertised. Their software could be better, and can be confusing to configure, but when properly configured, it just works.... We were assisted by Practical Preppers ( Engineer775 ) who did all the electrical plans, multiple video consults, and programmed everything for us.
