I have a solar system (solar panel, controller, battery and inverter). Battery have standby use 13.6-13.8V, cycle use 14.5-15V. I set the charging voltage to 13.8V.
The problem is that inverter to 230 AC is designed to 12V and it disconnect on voltage about 13.4V. (So it disconnect when solar is connected and charging).
How I should reduce the voltage for the inverter? (and keep it optimal for the battery)
