8.4. Battery's back up time depends on the appliances, which you will use
The batteries must provide between 10.5 and 15.5 volts DC and must be able
to supply the necessary current to operate the load. The power source should
be a well-conditioned deep-cycle lead-acid battery. To obtain a rough estimate
of the current (in amperes), the power source must deliver; simply divide the
power consumption of the load (in watts AC) by 10. Example: if a load is rated
at 100 watts AC, the power source must be able to deliver: 100/10=10 A.
For larger applications, the power source of several batteries may be connect-
ed in parallel. It is important to make sure that the cables have enough size.
This manual does not describe all of the possible types of battery configurations,
battery charging configurations and battery isolation configurations.

Battery charger

We recommend the use of deep cycle batteries. If you hear the alarm of
low voltage protection, please stop to use
can use it again. Please plug into the public power to charge for the battery.
To fill up a 150 Ah Battery, you will need about 15 h at 10 A.
How long to use the inverter: The battery operation time depends on the battery
capacity (Ah) and the loading power (Watt).
The method to calculate the operation time is:
Battery capacity (Ah) x 12 (V)/loading power (W)
Example

= 150 Ah (use <50 %)
