Review on π Efficient Solar Charge Controller: PowMr 20A Solar Panel Battery Controller with Dual USB, LCD Display, Timer Setting, and Adjustable Parameters by Randy Jagers
Does not load. - Solar and wind power
The actual voltage is one volt lower than the voltage on the display. This applies to both the battery and the charging voltage. The charging voltage also never exceeds 11.9 on the display or 10.9 in reality. I connect the charger and the battery charges and floats. This is for a boat and I need a reliable and accurate device. The component must be incorrect on the board or not calibrated. If it's only 12, every volt counts. i will return it I have no time for that.
- good thing
- expensive
