Hi,
I am planning to create small solar power source for 12V LEDs.
I need about 350W continuously.
Idea is to use one 280Wp panel with PWM/MPPT, but instead of battery connect 24V PSU with diodes array so it wont backfeed the PSU. If I am right, it should use solar power first (slightly higher voltage - 28V) and then take the rest from PSU (24V). I think the solar charger unit will detect the voltage from the PSU and think it is battery at ex. 60% state of charge.
Is it possible (and wise) to use it this way and use as much solar energy as it is possible during the day? I don't want to use mains voltage, just because the price of the 230V hybrid system is not worth it.
