A: The LiTime 12V/24V 30A MPPT Solar Charge Controller can work with standard off-grid 12/24V solar panels with high voltage or multiple panels with voltage up to 100V. And the maximum combined input solar power is 520W for a 12V battery system or 1040W for a 24V system. LiTime 12V/24V 30A MPPT Solar Charge Controller’s default setting is for 12V LiFePO4 battery. But it’s also compatible for 24V LiFePO4 battery, Sealed, Gel Lead-acid batteries by adjusting the parameters.
A: There is a practical limit though, if the solar array is too large then the power is just wasted, since the charge controller is always limiting the output. A typical recommendation is to limit the solar array to 110%-125% of the maximum controller rating.
A: LiTime solar charge controllers regulate the current from the panels to a safe level so it can charge the batteries. A 30A controller is adequate for a 300 watt solar panel set up.
A: LiTime solar charge controllers use maximum power point tracking (MPPT) technology which optimize solar production and control the battery charging voltage to prevent overcharging.
A: When the battery voltage reaches a point where the battery charger decides that the battery is full, the charger will cut out, and stop drawing power from the MPPT controller. In other words, the battery charger will present a high impedance to the MPPT controller.
A: No! MPPT solar charge controllers help to flow the current efficiently into your depleted battery. If we connect an MPPT solar charge controller directly to the inverter, your soalr system can get damaged, but if not damaged, there will be zero input in the inverter. So connecting MPPTs directly to the inverter is a bad idea!
A: You take the total watts of the solar array divided by the voltage of the battery bank. That will give you the output current of the soalr charge controller. For example, a 1000W solar array ÷ 24V battery bank = 41.6A. The rating of the charge controller should be at least 40A.
