 Decide What You Want Backed Up Home battery backup systems can keep the lights on and refrigerator running when the power goes out. With more battery capacity, such systems can also keep your air conditioning running. Decide which appliances are critical to your needs in a power outage, or plan for your whole home to […]

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

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 […]

Batteries – DC Coupling

Grid-Connected Solar Plus Batteries – DC Coupling February, 2014   DC Coupling is the standard method to combine a grid-tied solar system with batteries to provide power to your house when the grid is down.  In this approach, DC electricity is fed from solar panels to a charge controller and then to batteries.  The batteries […]

Batteries + Solar – Secure Power Supply


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.  […]
