60A Solar Charge Controller 12V/24V MPPT Solar Charge Controller, Adjustable LCD with Timer, Dual USB Ports, for RV, Boat, Cabin, Off-Grid Systems, Compatible with FLD/LiFePO4/SLD/GEL/AGM

Why isn’t the mppt solar charge controller recognizing my solar panels?

Polarity: Confirm all polarities (+ to +, - to -)

Battery: Ensure voltage >10V (12V) or >20V (24V).

Panels: Measure Voc <50V for 20A controller, or <100V for 30A/40A/60A models.

Wiring: Use proper gauge: 10AWG for 20A/30A, 8AWG for 40A, 6AWG for 60A.

What is the maximum solar panel voltage for 60A MPPT solar charge controller?

The maximum PV input voltage is 100V for both 12V and 24V systems. This means the total Open Circuit Voltage (Voc) of all your panels—even in cold weather—must stay below 100V. We recommend keeping it under 90V for a safe margin.

How much solar power can I connect to this mppt solar charge controller?

The max solar power depends on your battery voltage:

12V battery: Up to 240W

24V battery: Up to 480W

This applies to all models (20A/30A/40A/60A).

Do not exceed these wattages to avoid overload.

Can I connect multiple solar panels in series?

Yes, you can connect panels in series as long as their combined Voc stays under 100V. For example, you can safely connect three 30V panels in series (90V total). Always check the panel’s Voc label before wiring.

Is this solar charge controller compatible with lithium batteries?

Yes, it works with 12V/24V lithium batteries that have a built-in BMS. The controller auto-detects the system voltage. Do not use lithium batteries without BMS protection.
