8. SAFETY INSTRUCTIONS
The PB 300 XL is an off-grid system, which means it cannot be connected to the supply grid.
The following instructions should, therefore, be read before any installation takes place:
1. DO NOT attach any part of the PB 300 XL or any system that it is part of, to mains grid supply.
2. When installing any system using the PB 300 XL, ensure a certified electrical engineer is present to
check the system is assembled correctly and safely.
3. Although the PB 300 XL is built into a weatherproof box it is advisable to place a rain/sun shelter or
awning over the top.
4. When installing the cabling between solar panels and the PB 300 XL, ensure the wiring is not
connected to the panels until the circuit is assembled and complete.
5. The PB 300 XL should not be positioned near any flammable material or in any location which may
accumulate flammable fumes or gases.
6. Make sure the vent holes and fan grill are not obstructed to prevent overheating.
7. Only used approved cabling when making a solar power system.
8. PB 300 XL is designed to use 2 x 443Wh lithium-ion battery packs. No other source of power should
be used.
9. DO NOT immerse the PB 300 XL in water; it is not waterproof.
9. TROUBLESHOOTING
Once the Power Bank 300 XL is set up, there is very little to do. However, if there is no power coming
out of the PB 300 XL (after 24hrs), please check the following.
The switches are on and set to night only or 24 hrs.
The wiring from the batteries is firmly connected to the main circuit board.
The cabling coming from the solar panels is properly connected to the PB 300 XL via one of the two
terminals.
The solar panels are exposed to the sun for at least 6 hours a day.
There is no obstruction to the solar panels blocking the sun’s rays.
OVERLOADING - If too many appliances are connected to the PB 300 XL, it will shut down.
In that case, unplug those appliances and wait 5 minutes while the system resets itself. Then reattach
a reduced number of appliances (reduce the load).
