A Simple Operation
The system derives most of its energy through the solar
Photovoltaic (PV) array. The
PV array supplies DC power to the inverter during the day and at
the same time charges a bank of batteries.
The inverter converts the DC power into AC at 120/240 Volts
as required to operate your appliances.
At night time the batteries supply power to the inverter
thereby providing reliable power 24 hours a day.
There is a DC generator in the system to charge the
batteries during heavy energy usage or periods of poor sunshine.
The DC generator is more efficient and reliable than an AC
generators, however, are available
engineered as a system.
In a solar electric system there are many engineering factors
that should be incorporated into the system design to maximize
reliability and efficiency along with lowering maintenance.
incorporates Thermoregulation for longer component life.
combination of passive and forced ventilation keeps the inverter,
batteries, and generator running cool.
For each 10 degrees over room temperature the life of the
batteries is decrease by one half. In addition hot enclosures decrease inverter capacity and
reliability along with increasing the generatorís
in cool weather with conventional shelters, the heat build up from
the inverter and batteries under charge and or the generator
operation can raise the shelter temperatures to destructive

The base frame is constructed of welded 4" and 3" C channel for unitized
strength. The entire base is then hot dipped galvanized to protect
the welds and metal from corrosion.

Polar provides wires that are numbered on each end for
easier trouble shooting, optimum wire gages are used with the
correct circuit breaker capacities. Polar uses the very best 105 C and higher rated wire with
very long life insulation materials.
