Safe is most important for charging battery! CoHeart as R&D manufacturer of MPPT Solar Charge Controller considers all dangerous conditions during charging and build in complete protection to lead-acid and Li-ion batteries! Not only real MPPT circuit with accurate sampling sensor is adopted on input side,but anti-short-circuit protection is built-in on output side! This MPPT Solar Charge Controller is 20A for batteries voltage 120V/192V/240V/384V/480V/500V (max input current 20A) with wide solar input voltage range 100-400Vdc, easiler to configure solar panels in series than in parallel to save solar combiner box.
As very expenrienced manufacturer of MPPT solar charge controller, CoHeart also designed it built-in replaceable fuses, replaceable smart fan cooling to continue full power output all day without derating! Very robust even in Africa desert area! Now WiFi version is available to monitor your MPPT charge controller and solar system by phone APP!

Protections by manufacturer to MPPT charger controller：
• PV array short circuit
• Over discharging
• Over charging
• Patented Program to avoid puncture of Li battery PCBA*
• Load short circuit
• Over heating
• Anti adverse current
*Puncture Li battery protection PCBA: Normally MPPT or PWM solar charge controller will puncture MoSFETs of protection PCBA inside of Li-ion battery pack when cut off the charger from Li-ion battery under full charging, because the output of voltage will soar huge instantly! MPPT charge controller manufactured by us with our patented programming and technologies could avoid the voltage soar!
Settable Multi-Stages Charging:
Bulk Charging: the MPPT charge controller will charge batteries at max charging current.
Absorption Charging: When batteries voltage reach absorption voltage, constant-voltage regulation is used to maintain battery voltage at the absorption point, to prevent heating and excessive battery gassing. The battery will come to a full state of charging at the absorption voltage point.
After battery is fully charged in the absorption stage, the MPPT charge controller reduces the battery voltage to the Float voltage point(settable). The float stage provides a very low rate of maintenance charging while reducing the heating and gassing of a fully charged battery. The purpose of floating is to protect the battery from long-term over-charge.
Equalize Stage: start during period of 30 days. It will charge battery at a higher voltage to active the battery, usually 30mins, depending on different battery type. Equalize charging will prolong battery lifetime.
