Solar panels are a great way to produce electricity and save yourself some money. If you want one of these systems, then you will need a solar panel inverter to convert from DC to AC current to power the appliances in your home. There are a few things you need to consider before buying one. This article will give you a few tips on buying a solar panel inverter.
Your potential solar panel inverter can produce either a true or modified sine wave. True sine wave designs are much more efficient and are required for certain devices such as washing machines, fax machines, garage door openers, and electric motors. Modified sine wave designs produce an annoying sound but are much less expensive.
Another important consideration to make when buying a solar panel inverter is its wattage rating. You will need to determine how much wattage you need by adding the requirements for all of the devices you plan to use. If you only need enough power for small load, then you need a smaller inverter. If you buy a larger inverter, it will be much less efficient providing power for only smaller loads.
There are also different types of solar panel inverters. They include stand-alone, synchronous, and multi-function. If you won’t be able to produce enough power to cover your needs, then you’ll need a supplement from the power company. A synchronous inverter will allow you to do that.
This type of inverter also allows you to sell power back to the company if you produce more than you need. A stand-alone inverter doesn’t offer this capability but will be less expensive. Multi-function designs offer the benefits of both of these types but is by far the most expensive.
You may also want to ensure that your solar panel inverter is capable of producing a surge. Heavy equipment such as dryers, dishwashers, and power tools require a surge of power in order to startup. Therefore, your potential inverter must be able to produce this surge.
These are a few tips for buying a solar panel inverter. True sine wave designs are the most efficient but also the most expensive. Synchronous designs allow you to receive power from the utility company or sell power back to them if you produce more than enough.
