SMU solar charge controller is used for charging a solar battery that enters a deep discharge mode. If the battery capacity at the time of discharge reaches 8V per battery, it can charge the battery. Our offering prevents the battery from overcharging by controlling the voltage and current that travel from the solar panel to the battery. In addition to this, the said product uses MPPT (maximum power point tracking) to speed solar charging of the battery by up to 30% per day and is programmed at 15-A/200-W unit. SMU solar charge controller is highly efficient and durable.
