Do Solar Panel Need To Match The Controller. That way you get 11 7 x 5 2 60 watts going into your battery bank instead of 100 watts. An additional safety mechanism to protect the charge controller your batteries and appliances plus reduce fire risk is placing an appropriately rated fuse between the solar panel and the regulator. You don t need a charge controller with small 1 to 5 watt panels.
That way you get 11 7 x 5 2 60 watts going into your battery bank instead of 100 watts. If the panels are connected in series the voltage of each panel is added but the amperage stays the same.
I ll be powering music amplifiers and laptop with a total draw of about 8 amps ac using a 1500w inverter connected to a 12v battery.
I ll need a minimum of 5 hours run time with the solar panels charging the battery as i go. While the solar regulators of today are extremely robust. You don t need a charge controller with small 1 to 5 watt panels. By adding a dc dc converter in the blue solar mppt controller the system also becomes more flexible when we look at the input voltage of the controller.
