BATTERIES
Ensure the voltage indicated on your controller corresponds with your battery voltage!
Batteries are the most important part of a battery charging system and capacity should be sized
according to the load requirements and provide at least 3 days reserve. 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.
Follow these guidelines:
•
Deep Cycle batteries which are specifically designed for good performance in terms of
charge/discharge cycles must be used.
•
Suitable battery chemistries include lead acid sealed, non-sealed, Absorbed Glass Mat or
Gel. Other types can be used but may require different regulating voltage settings.
These can be factory set when ordering or using a Marlec interface cable and PC app.
•
Minimum battery capacities recommended: 400Ah @12v, 200Ah @24v, 100Ah @48V.
•
Only batteries of similar type, capacity and ideally the same manufacturer should be
connected in series or parallel.
•
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.7).
•
In series to increase voltage (Fig.8).
•
A combination of series & parallel to achieve desired voltage & capacity.
