Which charge controller of EPEVER support lithium battery?

The MPPT Tracer AN, XTRA N and Triron N series solar charge controllers can be configured to charge lithium battery storage devices. but the parameters of lithium battery must be set by app, PC software and MT50 display. It is important that these storage devices have their own battery management system (BMS), which does not require communication with the solar charge controller.

What are grounding specifications for Lithium Battery Solar System?

The controllers of EPEVER are divided into the common positive and common negative. If the common positive BMS and negative ground controller are used together, it would cause damage to the controller or lithium battery. Therefore, when configuring a lithium battery solar off-grid system, please select the corresponding controller according to the BMS specifications (a lithium battery with a common anode selects a controller with a common anode.)

Can the charge controllers of EPEVER be connected in parallel?

Only the MPPT Tracer 50A-100A charge controllers support up to 6 units in prallel by using a parallel adapter (PAL-ADP-50AN). After adding the parallel adapter, the charging current of each controller can be adjusted automatically in real-time. The charging operation status of the controller is automatically adjusted according to the battery charging state to improve the redundancy of the entire photovoltaic system.

What is multi-stage charging (bulk charging, constant charging and float charging)?

Bulk charging In this stage, the battery voltage has not reached constant voltage (Equalize or Boost Voltage) yet. The controller operates in constant current mode, delivering its maximum current to the batteries (MPPT Charging). When the battery voltage reaches a preset value, it will switch to Constant Charging. Constant charging When the battery voltage reaches the constant voltage setpoint, the controller will start to operate in constant charging mode, and this process is no longer MPPT charging. In the meantime, the charging current will drop gradually, and the process is not the MPPT charging. The Constant Charging has 2 stages, equalize, and boost. These two stages are not carried out constantly in a full charge process to avoid too much gas precipitation or overheating of the battery. Among them, equalize charging starts only on the 28th of each month. a) Boost charging The Boost stage maintains 2 hours in default (user can adjust the constant time and preset value of boost voltage according to demand). When the duration reaches the set value, the system will switch to floating charging. b) Equalize charging Some types of batteries benefit from equalizing charges regularly, which can stir electrolytes, balance battery voltage, and accomplish chemical reactions. Equalizing charge increases battery voltage, higher than the standard complement voltage, which gasifies the battery electrolyte. The equalizing charging time is also 2h by default (settable). Equalize charge and boost charge are not carried out constantly in a full charge process to avoid too much gas precipitation or overheating of the battery. Floating charging After the Constant voltage stage, the controller will reduce the charging current to the Float Voltage setpoint. This stage will have no more chemical reactions, and all the charge current transforms into heat and gas at this time. Then the controller reduces the voltage to the floating stage, charging with a smaller voltage and current. It will reduce the temperature of the battery and prevent the gassing and charging the battery slightly at the same time.

How to set lithium battery parameters in “USER” mode?

When selecting the “User” type to set the parameters of the lithium battery, the following precautions must be followed: 1) The control voltage parameters must be set by referring to the specifications of the lithium battery protection board, and the accuracy requirement of the lithium battery protection board is not greater than 0.2V. If the deviation is greater than 0.2V, which causes an abnormality in the system, EPEVER shall not directly or indirectly be liable for any loss or danger. 2) The temperature compensation coefficient is changed to 0; 3) The equalized voltage and the boosted voltage are the same, and the time is the same; 4) Each voltage point must follow the following logic. a. Overvoltage Disconnect Voltage > Over-Charging Protection Voltage(from BMS) +0.2V; b. Overvoltage Disconnect Voltage > Overvoltage Reconnect Voltage ≥ Charging Limit Voltage ≥ Equalize Charging Voltage = Boost Charging Voltage ≥ Float Charging Voltage ＞ Boost Reconnect Charging Voltage; c. Low-voltage Reconnect Voltage ＞ Low-voltage Disconnect Voltage ≥ Discharge Limit Voltage; d. Under-voltage Warning Reconnect Voltage ＞ Under-voltage Warning Voltage ≥ Discharge Limit Voltage; e. Low-voltage Disconnect Voltage ＞ Over-discharge Protection Voltage(from BMS) +0.2V; Warning: Please choose a lithium battery controller for lithium battery applications. It is not recommended to use a non-lithium battery controller to charge the lithium battery. If the system fails due to the use of a mismatched controller, EPEVER shall not directly or indirectly be liable for any loss or danger.
