Description of Functions
1. Suitable for charging 12V/24V/36V/48V lead-acid batteries, including GEL, Sealed, Flooded battery
2. Mainly suitable for off-grid solar power generation systems, such as: home solar power generation system, solar RV power generation,
boat, unattended base stations, outposts and so on.
3. MPPT charging technology, three-stage charging mode, constant current charge-constant voltage charge-floating charge,
effectively improve the battery charging efficiency. It is more portable than ordinary PWM charging.
4. Suitable for high voltage input, PV voltage up to 150 V (At the lowest temperature -25℃).
5. input two Channel solar panels at the same time.
6. This product adopts intelligent single-chip microcomputer design, and all workflows are controlled by software, which can achieve
high precision and high reliability.
7. The charging mode of high-efficiency MPPT is adopted to ensure that the battery works in the best state and greatly prolong the
service life of the battery.
8. It has full automatic control such as overcharge, overdischarge, overload protection, anti-reverse protection and so on
Attentions
The charge regulator is intended for use in photovoltaic systems with 12V or 24V nominal voltages, It shall be used
with vented or sealed (VRLA) lead acid batteries only.
Safety Recommendations:
1.Batteries store a large amount of energy. Never short circuit a battery whatever.
2.Batteries can produce flammable gases. Avoid making sparks, using fire or any naked flame. Make sure that the battery
room is ventilated.
3.Avoid touching or short circuiting wires and terminals. Be aware that the voltages on specific terminals and wires can
be up to double of battery voltage. Use isolated tools. Stand on dry ground and keep your hands dry.

  • Page 1 6. This product adopts intelligent single-chip microcomputer design, and all workflows are controlled by software, which can achieve high precision and high reliability. 7. The charging mode of high-efficiency MPPT is adopted to ensure that the battery works in the best state and greatly prolong the service life of the battery.
  • Page 2 ■Input solar panel matrix power 1. the MPPT solar controller has the function of simultaneous input of two solar panels. In theory, the two solar panels can input different open circuit voltages and different power, and both can work normally. however, in order to balance the overcurrent inside the controller, it is strongly recommended that the solar panels of the same specification be used in both ways, which is beneficial to the service life and efficiency of the controller.

  • Page 3: Installation Instructions

    Installation instructions ！ Warning 1 .The wiring order must be in the prescribed order, first connect the battery, and then connect the solar panel. when you disconnect the controller you must first disconnect the solar panel. then disconnect the battery, and the two groups of solar panels are in no order.
