The SunSaver MPPT charge controller is designed for 12V and 24V battery charging from PV modules with a maximum open circuit voltage of 75V. Use up to three 36 cell modules in a series. It can be used with 200 watts of PV when charging a 12V battery and up to 400 watts when charging a 24 volt battery.
- Power Boost ? Maximum power point tracking provides an increase of amps from the PV array into the battery, an estimated 50-25% boost. - U se of high Voltage Modules ? In addition to 12 volt crystalline modules, you can use high voltage and thin film modules for off-grid battery charging. - Converts 24V to 12V, reducing power losses in systems with a long cable run between the PV array and the battery.
SPECIFICATIONS FOR MPPT CHARGE CONTROLLER - Maximum Battery Current: 15A - Maximum Open Circuit Voltage 75V - Maximum PV Input 200Wp (12V Battery) - 400Wp (24V Battery) - System Voltage 12/24V
SUNSAVER DUO Great for RVs, caravans, boats and cottages. It will charge two separate and isolated batteries at the same time, such as a house and an engine battery, based on user selectable priorities. Includes a backlit remote meter which may be mounted in or on a wall and displays digital and pictorial status information about the solar power system. Epoxy encapsulated for protection, is user adjustable via DIP switch or connection to a PC and has an optional. remote temperature sensor. 5 year warranty.
SUNSAVER PWM CONTROLLERS Constatn voltage pulse width modulaton (PWM) charing is a proven advance compared to the standard on/off. A step below the MPPTs. Field selectable for sealed or flooded batteries. Ruged anodized aluminum case and epoxy encapsulated electronics ensure durability and logevity. A temperature compensation sensor in the chare controller varies full charge voltage with temperature. They have LED charging and load control indicators in LVD modules.
