New roof asphalt shingle, 5.1 kW system, string inverter makes roof noises in
the morning, and afternoon particularly after dark
Creek and crack it finally stops late at night but restarts late morning and
stops mid afternoon most days then intensifies after dark. Timing seems to
follow tempe
Maybe another possibility if the generator is a non-starter:
1) Sealed Batteries (no maintainance) appropriately sized for the running load
only, no motor starting surge
2) Single Sunny Island 5048 inverter (the most reliable IMHO)
3) 6 kVA autotransformer (boosts SI output to 240V)
4) 240V single
HI Daryl;
Your experiences with the water pump got me to thinking that a water pump has a
MaxPowerPoint as well. (Flow rate x head)
As you varied the flow rate, you were also MPPT ing the pump- inverter system.
You found max current at the middle of the pump's range, just like a solar
module.
