only for DC Power.
• Never connect any appliance whose rated power is larger than the maximum power
listed in the below technical data list. otherwise it will automatically cut off
• Do not leave this battery back up in bad ambient environment
• Do not leave the battery back up in direct blazing sun light or expose it to extremes of
heat or cold, which can affect its service life If possible place the battery in the shadow
of the solar panel or your house or even a tree
• Do not dip the battery back up into water it is IP44
IP44 rated connector is often referred to as ‘splash proof’ and protects from objects

If the system indicator shows red always and the pump does not work even though
the solar module is in full sunlight more than one sunny day, please check the possible
failures below:
1. The charge yellow indicator doesn’t lighten - check connection to the solar module
2. The battery is out of its service life and need to be replaced. Replace the battery by
the following the steps. Turn the unit upside down, undo the 4 screws, take the lid off,

to the solar panel directly and the pump will get almost the same performance on
sunny days.
