[RE-wrenches] Low Frequency transformer off-grid inverter options

[Dave Angelini Offgrid Solar]

Happy to hear that ! When it is on the market and gets reviewed and 
tested for split phase balance, surge, and has a networked/monitored all 
in one power system it will be great.

Costing, a 10 year warranty and training also.
