A power grid-connected pv inverter converts DC (Direct Current) power from wind or your solar charged battery into AC (Alternating Current). Something that plugs into a wall outlet in your home runs on AC.

Grid-Connected PV Inverter

RV (Recreational Vehicle) power grid-connected pv inverters are designed to be used mounted solar panels. Having an RV solar power system is like having a mini onboard power plant. It allows you the freedom and flexibility to camp out where there’s no normal power source; what’s commonly known as living off the grid.

The best technique for mobile solar powered success is investing in a correctly sized power grid-connected pv inverter. As with everything else, when you purchase an RV power grid-connected pv inverter you get whatever you pay for.

A well made power grid-connected pv inverter will not overheat while providing the electricity to run your small appliances and should be efficient at all input levels, tough enough to resist altering surroundings.

Grid-Connected PV Inverter

Various brand name grid-connected pv inverters contain Magnum Outback, Xantrex and Go Power Electricity. Picking and installing a correctly sized grid-connected pv inverter is a job best left to your own local RV professional or alternative energy store.

In order to pick out an RV grid-connected pv inverter through¬†perfectly suited to your own needs, you’ll need to provide some basic information to your local professional.

You need to understand what appliances are likely to be powered with the system, how much power they
Consume (amp/hours) , and the phantom load.

Phantom load is the electricity consumed by an appliance when it is turned off. The worst offender is that cube shaped transformer used to charge cell phones, although your television set is one example. These transformers are 60% to 80% inefficient and ought to be unplugged when not in use.

Each appliance’s electricity consumption is expressed regarding AC amps or AC watts, and is stated somewhere on the appliance itself. What the RV owner actually needs to know is the equivalent in DC amps, since that’s what the battery bank is supplying.

Where an appliance’s electricity consumption is expressed in terms of AC watts, one can use a simple formula to calculate the equal power expressed in DC amps:

DC Amps = AC Watts / 12 volts

Example: Seek out an grid-connected pv inverter with three distinct charging speeds: a mass charge at 100 amps; subsequently falling to a lesser rate as the voltage increases in the battery bank; and eventually applying a float charge only sufficient to maintain the batteries in a fully charged condition. The result is much quicker recharging of the batteries, either from tow vehicle alternator or the motor home or from shore power.

A top quality solar panel can produce about 3 amps of power during day hours. A conservative estimate for sunny weather might be 6 hours of full solar power every day and somewhat more during summertime. Hence one panel would place 3 panels 52 amps; and about 18 amps back into the batteries; 2 panels 36 amps.

Control mechanism and the distant monitor mounted inside the trainer performs a wide range of functions pertaining to both the grid-connected pv inverter and charger functions. It also has the basic “on/off” switch for the grid-connected pv inverter.If working in the grid-connected pv inverter manner it’ll let you know the present amount of amps being used up and the present voltage.

If in the charger mode, it shows the present amount in, in addition to the voltage where it is being charged as well as various warning functions and overloads.Clearly this is not a “one size fits all” choice. Especially important is the need when ascertaining whether or not an grid-connected pv inverter will be a valuable resource to consider your RV lifestyle.
