Power Inverter Comparison
Compare Apples to Apples: This simple principle applies to all purchases, of course, but don't be fooled by price. Don't purchase by brand name alone. Be sure that the power inverter you are purchasing is rated for the wattage that you require.
Bet on this: you will get what you pay for.
Brands to look for
Quality brand names include:
- Beacon Power
- PV Powered
Output Power is rated in wattage. You will need to be certain of the maximum wattage output of your solar panel or panel array, then match this wattage.
Surge Power is provided in a rating that is much higher than the output power rating-usually two, up to six times.
Efficiency should exceed 90%. The inverter's function is to convert Direct Current (DC) to Alternating Current (AC), and this process naturally loses some power.
Cost is important to you, of course. But you have to know that you get what you pay for. There are really very few "sales" in the solar industry (as of 2005, anyway)- because the demand for solar keeps increasing and the manufacturers are working to keep up with demand.
