Backup Generators

Backup Generators

In many cases, a backup AC generator is a required element in a stand-alone Renewable Energy system. It is usually not practical to design a battery bank capable of storing more than 3-4 days of power for any RE system, both because of costs and charging factors. The generator type and size are both important to your ability to charge your power system effectively. Brands that seem to work well are Kohler, Generac or Onan. However, it has been our experience that the more hours you run a propane fueled unit, the more maintenance issues you will have after the first 1000 hours with these units. Planetary Systems is now recommending that your use an inverter type generator with lower kw output and connect it with an external battery charger like a Outback GVFX inverter do not attempt to power your home and charge at the same time. See more about this below.
