BATTERIES
Leisure/Deep Cycle batteries are specifically designed for good performance in
terms of charge/discharge cycles. Batteries are the most important part of your
battery charging system and should be sized according to your load requirements
and provide at least 3 days reserve capacity. This will reduce cycling, prolong the
life of the battery and ensure system reliability during periods of low wind.
If in
doubt about battery sizing, contact your dealer or the manufacturer.
The minimum battery capacity recommended is 400Ah @ 12v, 200Ah @ 24v
Permanent connections should always be made to the battery terminals. Never use
crocodile clips or similar devices. Battery terminals should be well greased with
petroleum jelly or similar.
Batteries may be linked as follows:
In parallel to increase amp hours (Fig.8).
In series to increase voltage (Fig.9).
A combination of series & parallel to achieve desired voltage & capacity.
Only batteries of similar type & capacity & ideally the same manufacturer should be
connected together in series or parallel.
Ensure the voltage indicated on your controller corresponds with your battery
voltage.
