Why Are My Inverters And Solar PV Array Not The Same Size?

enphase m250

A common question in solar is “Why are you installing a 260 watt solar module on a 215 watt microinverter?” Or for central inverters, “Why is my system a 9,000 watt system on a 8,000 watt inverter?” Solar modules don’t produce their nameplate (DC) rating even with perfect sunlight that is perfectly oriented to the […]

Backup Generator For Solar System Array

off grid solar battery article1

So you now that you have gone solar, what can you do to fully cut the cord and go off-grid? A backup generator may be the answer. Generators can run loads that are beyond your inverters capacity such as well pumps and certain heavy machinery. If you have a battery backup as well, the generator can charge your batteries or improve their performance through a process known as equalizing. We serve Columbia, St. Louis and Illinois.

Off-Grid + Solar

Off Grid Battery System

Off-Grid Solar Battery Systems March, 2014         Off-grid solar systems were the starting point for much of the solar industry years ago.  Now, the majority of solar arrays are connected to the grid with a relatively small percentage of those providing battery backup.  However, for certain, select customers, an off-grid system may […]

The Utility is Down and the Sun is Up – You’ve Got Power (Without Batteries)! January, 2014   As previously discussed, there are now numerous options to have safe, secure power when the grid is down.  In the past, this was essentially considered an “all-or-none” option – either you had the grid with no solar […]

Batteries + Solar – Options

Considering Solar and Batteries?  Welcome to Your Updated Options. January, 2014 The solar market continues to develop at a wonderfully rapid pace.  One of the primary reasons to consider solar has always been energy independence.  For some, independence was freedom from power outages – or, even more so, complete independence from the electric grid itself.  […]
