Products Introduction MPPT solar controller is an advanced maximum power point tracking(MPPT) battery charger for off-grid photovoltaic(pv) systems .The controller features a smart tracking algorithm that maximizes the energy input from the PV and also provides load control to prevent over discharge of the battery . Key Features and Benefits 1. Maximizes Solar Energy Increase at least 15% to 30% charge efficiency compare to PWM Almost no power losses Excellent performance at low solar levels Recognition of multiple power peaks during sun shading or mixed PV arrays 2. Use of high Voltage Modules Enables the use of high voltage and thin film modules for off-grid battery charging 3. Smaller Size MPPT Mechanical dimensions are less than other MPPT controllers,making it easier to install in small equipment enclosures. 4. High Reliablity Efficient electronics, conservative thermal design and tropicalization results in high reliability and longer life 5. Fully Adjustable User selection via, on-board switches or PC connection 6. Extensive Electronic Protections Fully protected against most system errors and faults 7. More information The status LED’S and optional meter provide extensive controller and system date system voitage : 12 volts / 24 volts max battery current : 10 A max load current : 2 A humidity : 100% non-condensing tropicalization : epoxy encapsulation , conformal coating , marine rated terminals solar inverter MPPT lowest cost with highest quality longest using life best after-sale service from linkone
