Inverters
Inverters are the
hart of all PV systems. They convert DC to AC to supply
usable power to the home. They also can be a charger,
converting AC, from a generator or the grid, to DC to charge
a batteries bank. Inverters can remote start a generator and
monitors the heath of your battery bank. They also provide
info on system performance.
In the 90's we
installed the Trace (Zantrex) SW Series Inverters. We have
extensive experience servicing these older inverters and
have used replacements available.

For larger systems,
Outback inverters can be stacked together to supply the
power needs for larger loads.

Trace (Zantrex) inverters supplieing 120/240 VAC
In the early 2000's
we switched over to the new Outback PS-2 Inverter system. A
couple of years ago Outback introduced the Flexware line of
equipment which is now the industry standard. We presently
stock, sell, install and service Outback inverters and are
very pleased with their performance.

PS4
Zantrex (previously
Trace) has updated their inverter to the XPseries. This
inverter would be a good choice when both being Grid Tied
and having Generator back-up requirements

Charge
controllers
The charge control main purpose is to protect the main
batteries from being over charged buy the array. The Outback
MX60 is a popular charge controller due to its ability to
"Max Power Point tracking" allowing A high input voltage and
a more efficient charging capability. The MX60 also support
Equalizing and logging statistics of impute power from the
array.

The charge control is limited in capacity, more than one
charge controller is need for larger systems.

Battery
Storage
Our most commonly
used battery is the L-16 scrubber battery. This battery is
sold in high volume to industry so it is the most
economically feasible. These batteries need maintenance such
as adding water, equalizing regularly and possibly dealing
with acid spills. These batteries must be vented to the
outside to remove the hydrogen gas buildup when charging.
Three out of four systems we are involved with will use this
type of battery. We consider this battery the work horse of
the industry.
Custom
build battery box
Maintenance free batteries are also available. They don't
need water to be added or need to be equalized. They do not
vent hydrogen gas so venting is not necessary.

L-16
batteries
We
make our own custom made battery boxes out of 2in angle
steel. They can be made to mach any number and size of
batteries. A vent fan is
installed that vents the Hydrogen out of the box when
battery gases.
