2.5 Batteries
WARNING
Explosive gases can be generated by the house battery during the charge process,
therefore the battery should be kept in a well ventilated area.
WARNING
When charging a battery, make sure the settings at the Battery Setup menu on
the Remote Monitor are correct for the type of battery under charge. Charging
a battery with the wrong profi le may cause the BMS to indicate a fault or
give misleading results and could result in damage to the battery. Noticeable
oscillations between Boost and Absorption stages indicate the wrong choice of
battery type. Check and adjust battery type. If you are unsure of the battery type
or settings to use, set the BMS to the Gel setting.
Figure 2.5.1 and 2.5.2 show standard wiring for batteries in series and parallel
respectively.
To ensure that all batteries are equally charged, loads and BMS should be
connected with ground and 12V power connected diagonally opposite across all
batteries as shown in Figure 2.5.2.
To work out Ah rating of batteries in parallel simply add the rating of each battery
in the bank together. For example, 3 batteries with an Ah rating of 100Ah each will
yield a total of 3 x 100Ah or 300Ah. Batteries connected in series will assume the
lowest Ah rating of the batteries in the bank. For example, 2 batteries in the bank,
one is 50Ah the other 100Ah. When connected in series the Ah rating is 50Ah.
