A charge controller or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. They regulate the voltage and current coming from the solar panels going to the battery. Most 12V panels put out about 16V to 20V, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged.
Outback Power FLEXmax
The Outback Power FLEXmax family of charge controllers is the latest innovation in Maximum Power Point Tracking (MPPT) charge controllers from OutBack Power. FLEXmax MPPT Charge Controllers are the only choice when you demand a high performance, efficient and versatile charge controller for your advanced power system.
The innovative FLEXmax MPPT software algorithm is both continuos and active, increasing your photovoltaic array power yield up to 30% compared to non-MPPT controllers. Thanks to active cooling and intelligent thermal management cooling, both FLEXmax charge controllers can operate at their full maximum current rating, 60 Amps or 80 Amps respectively, in ambient temperatures as high as 104F (40C).
TBB Solar Mate
TBB Solar Mate solar charge controller with built-in Maximum Power Point Tracking (MPPT) technology enables it to increase the output from a solar photovoltaic (PV) array by as much as 30% compared with non-MPPT designs.
Solar Mate can optimise the PV output and eliminate fluctuation due to shading or temperature variables. It is a multi-voltage MPPT with built-in sophisticated battery charging algorithm for both lead acid battery or lithium-ion battery, which could support a wide variety of system designs. Meanwhile, the data management of 35 days of history record reveals the actual performance of the system.
Thanks to its self-cooling design, it is suitable for most rugged environments. All products in this range can operate at their full rating in ambient temperatures as high as 40 Degrees Celsius.
