I recently installed a solar inverter system with the following setup:

1. 4 solar panels (each 300watt) = total 1200watt
2. 24v inverter system
3. 2 units of 230amp battery
4. 60amp PWM charge controller

My load at max capacity is 500 watt and could go as low as 300watt during midnight hours.

But I noticed that my battery charge depletes faster than its charging, is it supposed to be so? What i mean is, my battery could be 26v after fully charged with no load, but after 4 hours of use, it falls down to 24.5v even when the solar panel is still charging the system.

So I am beginning to wonder if this is normal or there is a problem with my system configuration or the charge controller itself since i am using a PWM cc.

Please gurus in the house, i need your input.
