Features 1Upgraded Charging Algorithm: Periodically or over discharge equalization charging for the battery effectively preventing battery imbalance and vulcanization and extending battery life. 2Parameter Adjustable: Using temperature compensation the charging parameters can be automatically adjusted. Automatic identification of 12V/24V system voltage. With power off memory function. 3Electronic Protection: The advanced load starting method is adopted and the large capacity load can also be started smoothly. Provide overcharge overdischarge overload short circuit protection. 4Intuitive Operation: LCD screen and one key man machine interface are provided. User friendly browser and dynamic interface design ensure convenience and speed. 5Industrial Grade Design: TVS light protection can work in all kinds of harsh conditions. Two solar panels can be connected more efficient than other controllers.
