Hi All
I'm having a problem with the alarm on the inverter going off & shutting down when the batteries are full. I've noticed that the Voltage shoots up to 15.5 volts. I believe that this happens when a heavy user of the power shuts down, like the washing machine or freezer. I've set the POWMR VR to 14.5 volts absorption but I don't think that it's taking a lot of notice. I have checked the batteries with a cat111 Multi tester & recorded 15.3 volts. This voltage is very brief. The Inverter is 3500 Watt Pure Sine Wave.
This Off Grid System :- 8 Panels, four in series x 160 W each panel. Total 1280 Watt. Leads from panels to the connecting wire are 1.5mm Dia. The Connecting wire to the Shunt 3mm Dia. From the Shunt through the VC (60 Amp) & Batteries are 3mm X 2 wires.
Batteries are 4 x 100 Amp Hr Flooded & 1 x 200 Amp/h AGM. It's grown a bit like "Topsy" over time so liberal use of Anderson Type Plugs.
There is in addition a wind turbine but it's too low to provide much power. It's connected to the batteries via it's own VR.
Thanks for any advice.
