Feature:
1. High Tracking Efficiency: The maximum power tracking technology can still track the maximum power point of the solar cell in a complex environment, with faster response speed and higher tracking efficiency, and the tracking efficiency can reach up to 99.9%.
2. High Conversion Efficiency: The superior DC DC Battery Charger with MPPT makes use of design of multi phase synchronous rectification buck boost circuit enables high DC DC conversion efficiency in both high and low power sections, up to 98%
3. High Performance: The backup battery supports a variety of battery types such as sealed, gel, open, lithium and custom. Supports multiple generator types such as smart generators and traditional generators, and automatically identifies generator types through ignition signals.
4. Multiple Charging Modes: There are multiple charging modes such as photovoltaic charging the backup battery alone, generator charging the backup battery alone, photovoltaic and generator charging the backup battery at the same time, photovoltaic charging the starting battery, etc.
5. Multifunction: Backup battery charging voltage line loss compensation, which makes the battery charging voltage control more accurate. With backup battery temperature sampling function, battery supports temperature compensation, effectively prolonging the life of the battery. With high temperature charging automatic derating function.
6. TTL Communication: Provide technical support for communication protocol to facilitate secondary development and application of users. Support external remote switch to control charging. Parameters can be monitored and set through the mobile phone APP and PC monitoring and setting software.

Note:
1. We strongly recommend that fuses or circuit breakers are connected to the PV array side, load side and battery side to prevent electric shock hazards during wiring or misoperation, and make sure that the fuses or circuit breakers are disconnected before wiring.
2. The photovoltaic array may generate a high open‑circuit voltage, disconnect the circuit breaker or fuse before wiring, and be careful during wiring.
3. Once the positive and negative terminals of the battery and the wires connected to the positive and negative electrodes are short‑circuited, fire or explosion may occur. Please operate with care.
4. Please connect the battery first, then the battery board, and finally the load. When wiring, please follow the connection method of the + pole first, then the ‑ pole.
5. Note that the installation position of the battery fuse should be as close to the controller as possible, and the recommended installation distance should not exceed 150mm.
6. Never install the controller and the open battery in the same closed space! Also do not install in an airtight place where battery gas may collect.
