Deep-Cycle AC Battery Charger Operation
The battery charger is located inside the main housing unit with an external electrical plug /
outlet to allow the operator to provide a
rapid charge to the unit's battery bank. This
method is designed as a backup or
secondary way of charging the batteries.
The primary method to charge the batteries
is through the solar arrays and with a wind
turbine (if applicable). However, depending
on your geographic location, and solar
irradiation, there may be times of the year
when having a backup is helpful.
This option is especially useful for those with heavy system utilization, especially during long
winter nights (heavy use) and short winter days (low solar gain) or to obtain a rapid
charge for a same day rental / use for a system that has been previously charged.
For SLT/SLTW systems the backup battery charger is standard, the systems are prewired
and ready to use. Note: SLT/SLTWs come equipped with AGM, no maintenance, sealed
batteries The charger will come configured correctly for the type of batteries installed.
To Operate:
For a standard unit:
The charger plug is hardwired to the
unit. You will find the male plug end,
(as seen in picture) wrapped around
the cord wrap. Plug this into your local
AC power source using a 20amp
outlet. The Charger is pre-set to an
input or either 120VAC (for U.S.) or
230VAC (ex U.S., 50/60 Hz, 20A. Call
if you want to change it.
1) Turn the Charger power on (open door under solar wing, Charger is on back wall,
power switch is on right side of Charger unit)
2) The Charger will automatically start its 3 stage (bulk charging, absorption float),
temperature compensated charging.
a. Bulk constant charge
b. Timed Absorption/Boost
c. Float/Maintenance or "Trickle" Charge
