Charging

Waits a pre-determined 'warm-up period then switches over, allowing generator power to flow to the loads. The generator power is now running all loads in the house as well as powering the battery charger. Therefore the generator should be sized to not only run the battery charger at a high rate, but also any AC loads that may be running at the same time. If the generator is undersized for the loads being run, the battery charging rate will be reduced. This may mean the generator is run for a...

Generator Placement and Powersheds

Powersheds are a common outbuilding on the remote homestead. They often serve multiple functions of housing the generator, batteries and power conditioning equipment required with your PV system. Beyond this, they can also house tools and equipment as well as support the solar array if oiaced in a sunny, non-shaded area. It is a good idea to keep flammable fueis and gasses in a separate building rather than the building in which one sleeps. The sound insulation qualities of a powershed offer...

Used Batteries

Used lead acid batteries, especially large two volt telephone type cells can sometimes be found for sale. While used solar modules and inverters are usually an acceptable risK, used batteries are a high risk proposition. Should you consider them In our experience, it is difficult to know just how an older battery has been used. Has the previous user taken good care of the cells or have they been neglected7 Have they actually been load tested or just cleaned ud and recharged Our recommendation...

ShuntsfwM

What is a shunt A shunt is a device used to measure large DC current, typically the current flowing to and from your battery bank. In more detail a shunt is a precision resistor which produces a very accurate voltage drop when current is passed through the unit. This voltage drop is proportional to the amount of amperage flow, therefore by reading the miiiivoltage one can observe current flow on a properly calibrated meter. Do you need a shunt Depending upon the monitor you select, you may...

Battery Enclosures

Install your batteries in a warm, cry location. 55-80 degrees F. s the optimum temperature range lower or mgher than this and performance diminishes significantly. Because batteries produce a potentially explosive mixture of hyaro-gen and oxygen, venting is needed to orevent a builauD. 5ince hyarogen is lighter than air it has a tendency to rise, f venting is placed at tne top of the battery enclosure and air is Drought in from the bottom, this gas wiil move up and out of the battery area.
