Real-time energy statistics function, Overheating power reduction function. Provide 5VDC power through the dual USB output interface to charge electronic devices. Step: Connect solar system in the order of 1.battery-- 2. load-- 3.PV array ; and disconnect solar system in the reverse order 3. 2. 1. Battery must be connected first ! Never connect soalr panel array to controller Without/Before connect battery. DO NOT connect any inverter/wind/Alternator or Charger into the charge controller directly ! You should connect with battery and add fuse . If there is a long distance between the PV array and the controller or between the controller and the battery, larger wires can be used to reduce the voltage drop and improve performance. (Recommended wire size is only for reference.) Protection function : ? PV over current protection ? PV short circuit protection ? PV reverse polarity protection ? Night reverse charging protection ? Lithium battery low temperature protection? Battery over heat protection ? Controller overheating protection ? Battery reverse polarity protection ? Battery over discharge protection ? Battery over voltage protection ? Load short circuit protection ? Load overload protection How to program more detailed parameters for Battery? Via remote meter MT50 ; Via phone APP(Android or IOS) (Accessories needed: EPEVER-BLE-RJ45-D or EPEVER-WiFi-2.4G-RJ45-D ) ; Via PC software (Accessories needed RS485 cable :CC-USB-RS485-150U ) ,Software download website: EPever official website or read in manual .
