Solar Charge Controllers:
SolarBox stocks and sells PWM and MPPT charge controllers. They are both widely used to charge batteries with solar power. The PWM controller is in essence a switch that connects a solar array to the battery. The result is that the voltage of the array will be pulled down to near that of the battery.
The MPPT controller is more sophisticated (and more expensive): it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement of the battery plus load. It is generally accepted that MPPT will outperform PWM in a cold temperate climate, while both controllers will show approximately the same performance in a subtropical to tropical climate.
Victron- SmartSolar MPPT Regulators feature built-in Bluetooth. This allows you to monitor the solar performance via the Victron Connect App on your phone, perform firmware updates, change the charging profile and much more!
OutBack Power-The FLEXmax family of charge controllers is the latest innovation in Maximum Power Point Tracking (MPPT) charge controllers from OutBack Power. The innovative FLEXmax MPPT software algorithm is both continuous 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 104°F (40°C).
Schneider- The Conext™ MPPT 100 A 600 Vdc solar charge controller offers optimum system performance for DC coupled solar and storage installations, with easy, flexible installation of large PV arrays. With up to 6 kW of charging power, and allowance for over-sized arrays, the MPPT 100 is ideal for residential grid tied self-supply and off-grid systems and is scalable for larger installations. The MPPT 100 600 offers faster installations and lower balance of system costs with 2 string installations and is compatible with Conext XW and SW storage inverter solutions.
AERL- CoolMax SRX Solar Charge Controllers feature over 35 years of MPPT innovation, offering a superior tracking algorithm with an ultra-low loss, high-efficiency thermal design, backed by our Australian factory warranty and local support.
