[RE-wrenches] 3-phase with storage

[Dave Angelini Offgrid Solar]

The 2 Lithium batteries I use are HALT tested but it is always a big risk
with a battery that may out live many of the clients. The math on these
batteries has them lasting 30 to 40 years offgrid and that is pretty hard
to believe! Will the BMS fail or the battery?

If they can afford it I have them do both chemistries! Add a second
inverter and a lithium bank. They get power redundancy and the efficiency
is really amazing to someone living offgrid. Especially in winter of
course!

>From a single Conext XW+ unit to clusters up to 102 kW,
the Conext XW+ is a scalable system that allows for the
integration of solar capacity as required. I like Sunny also:)

> We are building a similar system presently, 60 kW Sunny Island Inverters,
