Solar Inverter Solar Inverter or PV Inverter takes current from the battery then converts it to AC current to be able to run any common appliances in your house. Sizes of inverters you need may vary, depending on your usage and the equipments or appliances that you have. An average house needs 4000-5000 watts continuous power, but yours may be more or less than that. To make sure, it’s advisable to make a list of all the equipments or appliances (those you frequently use) that you have and the duration (how long) you have to use these equipments. This is to determine the maximum continuous power and the size of inverter that your house needs.
Types of Solar Inverters
- Micro-Inverter – This type of inverter converts direct current (DC) into alternating current (AC) directly from behind each solar modules. It enables installers to design more easily and more cost-effectively solar systems. Micro-inverter typically has with 15-years warranty and is considered as reliable and highly efficient in producing more power.
- String Inverter – With this type of inverter, solar panels are wired in series, increasing the voltage and keeping the current low in order for the wire size be smaller and the wiring be simpler. String inverter is currently the type of inverter which is mostly used today, with a typical 10-20 years warranty.
- Central Inverter – A type of string inverter that is used in large-scale applications which presents a much easier installation compared to small-string inverter. It also offers higher efficiency, resulting to a much higher cost and a 5-year (extendable up to 20 years) warranty period.
