Am using 800watts sukam inverter and have 55watts panel. What controller can i use to connect my solar system to have a max power . Already i have 200 Amp/hr battery
If that 55-watt panel has an open circuit voltage of 7-8 volts, you may get more efficiency by omitting the charge controller completely, and connecting the panel straight to the battery. 55 watts is marginally too small for a 200 AH battery at 2 volts, by the way.
You need a charger Controller but 55 watt panel is not a whole lot of power. So yes you can buy a very good one but it will cost a lot more. For a 55 watt panel you only need a 4 to 7 amp controller. But why not buy a 0 amp so you can add a second solar panel etc... A PWM (Pulse Width Modulated) is the cheapest and most robust type MPPT (Maximum Power Point Tracking) These controllers actually detect the optimum operating voltage and amperage of the solar array and match that with the battery bank. The result is additional 5-30% more power out of your array versus a PWM controller So unless you have a system over 200 watt the PWM works very good I have two of the PWM myself
