SmartSolar MPPT Charge Controller - 100V - 30AMPFeatures:Bluetooth Smart built-in The wireless solution to set-up monitor update and synchronise SmartSolar Charge Controllers. VE.Direct For a wired data connection to a Color Control GX other GX products PC or other devices Ultra-fast Maximum Power Point Tracking (MPPT) Especially in case of a clouded sky when light intensity is changing continuously an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers. Load output Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage (48V model: interface with a relay). Alternatively an intelligent battery management algorithm can be chosen: see Battery Life. The load output is short circuit proof. Battery Life: intelligent battery management When a solar charge controller is not able to recharge the battery to its full capacity within one day the result is often that the battery will continually be cycled between a partially charged state and the end of discharge state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months. The Battery Life algorithm will monitor the state of charge of the battery and if needed day by day slightly increase the load disconnect level (i.e. disconnect the loa
