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.
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.
We strongly recommend that one of the voltage
regulators available from Marlec is fitted to
prevent batteries becoming overcharged in
strong winds and is essential with gel/sealed
batteries.
Batteries may be linked as shown in the figures
10 and 11. It is essential to observe polarity as
follows:
Red is + Positive
Black is - Negative
CABLE SPECIFICATION
The cable used for connection of the
Windcharger to the batteries should be in
accordance with table 1. The use of a smaller
cable than recommended will reduce the
performance of the charging system.
Cable and connectors are available from your
dealer or the manufacturer.
