How to utilize Excess Energy in a system with PWM charge controller
I am newly joined this forum and I like the depth of Technical discussions happening over here.
I am planning for a small Off Grid rooftop system, with panel 325Wp X 2 (parallel connection), 150AH X 2 Batteries with a 2200VA solar Hybrid Inverter (24V format) with the in-built PWM charge controller. The Solar charge controller has specification of 24V x 30A . The Panels has max Voltage 37.8V with max current of 8.6A. So during peak hours, I may get maximum 17A current with Avg voltage of 26 V depending on battery charging stage. That leaves with me around 200Watts of unutilized power while battery is being charged.
Can you plz suggest what are the possible ways to tap and utilize this power? I have read about water heater using excess energy. Are there any other possibilities?
Even if any ready-made solution is out there, what do I need to know so as to be able to use it alongside the afore mentioned Solar Inverter?
