Appendix: Use of Lead-acid Batteries
Selection of the Battery
Select a deep-cycle battery (e.g. lead-gel battery) as the power source for
the inverter. These batteries are designed for higher continuous loads and
cyclical discharges of up to 80% of their capacity without damaging the
battery.
Starter batteries are not suitable for operating an inverter.
Size of the Battery
When selecting the battery size, take the following into account: The
greater the battery capacity, the longer the inverter can be operated
without having to recharge the batteries.
Undersized batteries are often drained too deeply. This reduces their
efficiency and the service life of the batteries. The main causes of
premature ageing and defects are insufficient capacity, insufficient charging
and battery maintenance.
Wiring the Battery
Only connect batteries of the same type and size to each
other.
Never combine open and sealed batteries.
Clean the battery terminals with a brass wire brush.
Carefully fit the connecting terminals and tighten the clamping
screws.
Grease the battery connections.
Charge new batteries before use.

User Manual Appendix
Page 16 of 18
Connecting Batteries in Series
2 batteries connected in series
provide double the supply
voltage.
However, the total capacity does
not increase.
Example: 2 batteries 12 V / 100 Ah connected in series provide a supply
voltage of 24 V with 100 Ah.
Connecting Batteries in Parallel
2 batteries connected in parallel
provide double the battery
capacity.
However, the supply voltage does
not increase.
Example: 2 batteries 12 V / 100
Ah connected in parallel provide a
supply voltage of 12 V with 200
Ah.
Maintenance of the Battery
Lead-acid batteries must be maintained at regular intervals. The battery
must be maintained at least once a month in hot seasons and quarterly in
cold seasons. Older batteries should be checked every 14 days.
Maintenance of Open Batteries
With open batteries, check the condition of the liquid and measure the acid
density with an acid syphon.
To increase battery life, make sure the battery surface is clean and dry.
Carefully remove dirt and acid stains with hot water and a soda solution.
Remove the soda solution with fresh water and dry the battery. Ensure that
the venting flaps are clean and correctly fitted. Then check the installation
of the connecting terminals. Tighten the clamping screws if necessary.

User Manual Appendix
Page 17 of 18
Topping up Acid Level
Ensure that the cell grids are always covered with acid. Always use distilled
water to top up the battery, never normal drinking or sea water. Follow the
manufacturer's instructions when topping up the acid level.
Maintenance of Sealed Batteries
Sealed batteries require little maintenance. An inspection is limited to
measuring the battery voltage.
Storing the Battery
Store batteries in a cool, but frost-free and dry environment.
To prevent the battery from freezing, ensure continuous trickle
charging in cold conditions.
Never store batteries in a discharged state.
If stored for a long time, check the charge status regularly and
recharge if necessary.
