Page 2: Important Notes
• Before connecting battery always check battery and PV panel polarity. • If used with panels over 150W the BMPPT250 MUST be fitted with the PVF fuse. Locate this fuse as close as possible to the BMPPT. A 10A 32V fuse is recommended. - Page 3 Please read these instructions before use Settings And Configurations: The BMPPT250 factory default setting is for sealed lead acid batteries (Maximum charge voltage 28.4V and float voltage 27V) and auxiliary switch (grey wire) configured in Low Voltage Disconnect mode. The various operating modes can be configured with a combination of the green and yellow wires and the internal links CHE and REN.

- Page 5 Model: 250W Solar Charger BMPPT250 Booster Maximum Power Point Tracker Page 5 of 8 Operating Instructions Please read these instructions before use Wiring With Low Voltage Disconnect : The LVD option disconnects the load when the battery voltage drops below 0.85 of nominal voltage to protect the battery from damage.
- Page 6 Model: 250W Solar Charger BMPPT250 Booster Maximum Power Point Tracker Page 6 of 8 Operating Instructions Please read these instructions before use Wiring With Critical And Non Critical Loads: Critical loads are generally light loads which are powered under any condition. Non critical loads are loads which can be disconnected to ensure maximum on time for critical loads as well as to extend the life expectancy and reliability of the system.

- Page 8 Q: What is the smallest panel size for the BMPPT250? The smallest panel size recommended for the BMPPT250 is 10W, below that level the BMPPT will not function effectively. Q: Is interference possible? and If so what do I do? GSL’s BMPPTs produce far less interference than conventional solar regulator during the absorption and float stages, that...
