A charge ‍controller for an alternator⁣ is a device that regulates ⁤the charging ‍process of a battery or battery bank connected to an alternator. It ensures that⁢ the battery⁤ is charged ⁤efficiently and prevents overcharging or undercharging, which can lead to damage⁤ and reduced battery lifespan.

Some‌ of​ the key features of a charge⁤ controller for an⁣ alternator include:

1. Voltage regulation: The charge controller monitors the ⁣voltage⁣ level of the ‌battery and regulates ⁤the charging⁤ process accordingly. It prevents overcharging by reducing ⁣the ​charging current when the battery⁣ reaches its ‌optimal voltage level.‌ Similarly, it provides additional charging current when the battery voltage is below a certain threshold.

2. Temperature ​compensation: Charge controllers for alternators often have temperature sensors to ‍measure ​the battery temperature. This allows for temperature compensation, which adjusts ‌the charging voltage to⁢ compensate ⁢for the battery’s temperature fluctuations. By doing so, it ensures that

How to program for Lithium Battery?

Via PC software (Accessories needed RS485 cable :CC-USB-RS485-150U )
Via phone (Accessories needed RS485 cable :CC-USB-RS485-150U & OTG cable)
Via phone APP, Android or IOS system (Accessories needed:eBox-WIFI-01 or eBox-BLE-01 )
Software download website: EPever official website or read in manual



Step: Connect solar system in the order of 1.battery–> 2. load–> 3.PV array. 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.)
