Further System Requirements
Batteries
Leisure / Deep Cycle batteries are specifically
designed for good performance in terms of
charge / discharge cycles. Batteries are the most
important part of the renewable energy battery
charging system and should be sized according
to the 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.
We strongly recommend that one of the voltage
regulators available from Marlec is fitted to
prevent batteries becoming overcharged in
strong winds and during low energy consumption
periods. A regulator is essential with gel and
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
Fig 10. In parallel to increase amp hours
Fig 11. In series to increase voltage
Cable Specification
The cable used for connection of
the Windcharger to the batteries
should be in accordance with
table. 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.
