Intelligent control is realized by using microprocessor and dedicated control calculation.
Four load working modes: Pure lighting control, lighting control & timing control, hand operation and debug mode.
Scientific management of battery: as it is overcharged, the battery will get booster tension charge. As a result compulsory maintenance is available for the battery. In normal working state, the direct charge and floating charge are both available, so that the battery life-span is increased. Besides, the adoption of high precision temperature compensation makes the charging more accurate.
Comparing with the charging loops using diodes, the one that adopts double MOS series circuit control makes the voltage loss dropped by 50%. With the PWM fuzzy control in charging, the charge efficiency is improved a lot.
LED screen shows the working state of solar battery, storage battery and load. LED shows the adjusted parameter. In this way, users can learn the operation state in ream time. Besides, there are various choices for parameter; users can select the proper working mode based on the different conditions.
Various protections include over-charge, over-discharge and over-load, as well as unique electron short circuit protection and connection-reverse protection. All the protections are harmless to any parts and fuse. TVS thunder proof protection is also available. Non wire jumpers design improves the reliability and durability of the products.
Technical grade chips and precision components are adopted for all the controls. Therefore, the controller performs well in very low and high temperature, as well as humid environment. At the same time, with the use of crystal timing control, the timing function of controller is much more reliable.
Digital LED display and one button setup make the device easy to handle.
This is a smart solar charge controller which has advanced PWM technology. Solar charge controller is one of the important parts in the off-grid solar system.

Yes, all of our inverters provide a true pure sine wave output.
A pure sine wave output inverter matches the quality of the public power grid (or even better) with a low repair rate, long lifespan, no harmonic pollution, and complete appliance protection. Modified sine wave inverters can negatively impact sensitive electronics and cannot run inductive loads like air conditioners, refrigerators, or certain motor control circuits.
Our inverters can be used for household, office, agricultural, and other inductive loads such as refrigerators, air conditioners, water pumps, and more.
Simply share your power demands and load specifications with us, and we will recommend the most suitable inverter model for your requirements.
This refers to the input voltage from the battery bank. Higher voltages reduce the current, allowing the use of smaller cables between your solar panels and battery bank. Please note that the solar panels, inverter, and battery bank must all be configured to use the same system voltage.
If any product is faulty, please send us pictures or video evidence. Our engineering team will diagnose the issue and provide free replacement PCB board spare parts for after-sales service.
