Feature:
1. HIGH EFFICIENCY: Tracking efficiency ≥99.5%, maximum conversion efficiency is 98%, with 12V 24V automatic working system voltage identification, automatic saving function. Two voltage disconnection levels, has charging power and current limiting function
2. PROTECTION FUNCTIONS: Built in reverse polarity, overcharge, overdischarge, overload, short circuit and reverse current protection. Protect the battery from being overcharged by the solar module and overdischarged by the load
3. OPTIMIZED BATTERY LIFE: The 20A solar charge controller charging process is optimized to extend battery life and improve system performance. Includes 4 stage battery charging (batch, boost, float and equalization) and temperature compensation
4. SUPPORT BATTERY: Support sealed battery(default), or gel, AGM, Flooded user (9～17V at 12V; 18～34V at 24V), lithium battery for LiFePO4 (4s/12V; 8s/24V), Li(NiCoMn)O2 (3s/12V; 6s/24V). With battery temperature compensation function (only for acid batteries), overheating power reduction function
5. TEMPERATURE COMPENSATION FUNCTION: With RS‑485 communication bus interface and communication protocol, detailed parameter settings are set by accessories such as MT50, for eBox‑WiFi‑01, for eBox‑BLE‑01, for elog01, and PC software

Note:
1. Connect the system in order, battery‑load‑PV array, and disconnect the system in reverse order 3. 2. 1.
2. Never connect the solar panel array to the controller without batteries. The battery must be connected first! ! !
3. Do not connect any inverter, wind, alternator or charger to the charge controller!
4. If the remote temperature sensor is not connected to the controller, the battery charge or discharge temperature defaults to 25℃ without temperature compensation.
5. The wire diameter is for reference only. If the distance between the PV array and the controller or the controller and the battery is long, larger wires can be used to reduce the voltage drop and improve performance.
