Ⅶ. Care and maintenance
1). This series of products seldom need to be fix. The standard model battery is
like a adjusting tap. Low maintenance, ensuring better life only by charging
often. When connecting to mains supply, no matter whether the inverter is on
or not, it still keeps charging for battery, and provides over charge, over
discharge protection.
2). If there has been long time no using the inverter, it would be better to charge
on after four to six months.
3). The normal working life of battery is 3 or 5 years, if it doesn't work, please
change as early as possible by professionals.
4). Don't change the single battery , changing the battery should according to
the suppliers instructions.
5). In normal, the battery should discharge then recharge after working each four
or six months , start to charge and finish discharge, standard charging time
should be more than 12 hours.
6). In high temperature area, the battery should be charged and discharged
every 2 months and the standard charging time is more than 12 hours.
Note:
1). Before changing battery, must turn off inverter and disconnect the
mains supply.
2). Remove metal object like ring, watch etc.
3). Please don't put the metal objects on the battery.
4). It is a normal phenomenon that the wire will appear a small spark when
connecting to the inverter, but it will not does harm to the people or the
inverter.
5). Be attention to do not reverse connecting between the positive pole and the
negative pole.
If connected to the generator, the following steps should be required.
1).To start the generator till it runs steadily, then connect the generator output to
the inverter input terminal. And turn on the inverter step by step according to
the operating instruction. After the inverter starts, connect the load one by one
to the inverter.
2).Please select the inverter capacity two or three times over than the
capacity of the generator.
