OFF-GRID DC SOLAR POWER SYSTEMS
DC off-grid solar power systems are most often used to power DC appliances in RV's, boats, and cabins, as well as farm/ranch appliances like cattle gates and rural telecommunications systems when utility power is not accessible.
DC solar power is less expensive than AC solar power because an inverter is not required to convert the electricity produced by solar panels and stored in batteries from DC to AC. But DC solar power does NOT power standard AC appliances.
OFF-GRID AC SOLAR POWER SYSTEMS
Off-grid solar power also stores DC electricity in batteries. The addition of an inverter allows this system to convert DC electrical current coming from the batteries into AC or alternating current. AC is the standard form of electricity for anything that "plugs in" to utility power and is the appropriate current for common household appliances.
While AC off-grid solar power systems are more expensive because of the cost of the inverter, the appliances you are able to use are less expensive and there are more kinds of appliances to choose from.
OFF-GRID SOLAR POWER FOR REMOTE TELECOMMUNICATIONS
Small off-grid DC solar power systems can power tele- communications electronics in locations which are far away from power lines.
OFF-GRID HYBRID SYSTEMS
Off-grid solar power also stores DC electricity in batteries. The addition of an inverter allows this system to convert DC electrical current coming from the batteries into AC or alternating current. AC is the standard form of electricity for anything that "plugs in" to utility power and is the appropriate current for common household appliances.Hybrid Systems use a combination of solar panels, wind generators or gas generators.Gas generators are noisy, notoriously difficult to start, require more maintenance than an entire solar panel system and require you to haul fuel or have it hauled. Don't say we didn't warn you.
