Page 3: Safety Instrucitons And Waiver Of Liability
Dear Clients, Thanks for selecting OPTI-Solar SC MPPT series charger controller. Please take the time to read this user manual, this will help you to make full use of many advantages the controller can provide your solar system. This manual gives important recommendations for installing and using and so on. Read it carefully in your own interest and pay attention to the safety recommendations in it please. -
Page 4: Pruduct Overview
Magic series solar controller is based on an advanced maximum power point tracking (MPPT) technology developed, dedicated to the solar system, the controller conversion efficiency up to 97%. 2.1 It comes with a number of outstanding features, such as: Innovative Max Power Point Tracking(MPPT) technology, tracking efficiency >99.9% ... - Page 5 High Voltage Strings and Grid-Tie Modules Another benefit of MPPT technology is the ability to charge batteries with solar arrays of higher nominal voltages. For example, a 12 Volt battery bank may be charged with a 12-, 24-, 36-, or 48-Volt nominal off-grid solar array. Grid-tie solar modules may also be used as long as the solar array open circuit voltage (Voc) rating will not exceed the maximum input voltage rating at worst-case (coldest) module temperature.
