12 kw PV nominal. Low tilt angle and old panels so reality is far less. 5 e-vault 18.5 kWh batteries 4 SI 6048 2 SB 6000 US System operational for some years with flooded batteries. Just installed the e-vaults. I reset the system to factory defaults. I am not sure how to verify the system will

Friends: I’m kinda stuck on a project setting up a SI/SB AC coupled system off grid. When the SB inverters ramp up the battery voltage jumps to 69 pretty quickly and the system shuts off. I checked the mini-grid frequency and it does ramp up to about 62+ but apparently not soon enough to curtail

The volume of water in a Florida downpour can come on virtually instantly and would be many many times more volume of water than a residential hose. The rate of temperature change in a downpour will be many multiples of what a hose could do. This happens almost daily in summer here. A few hose
