The main types of inverters are string inverters, and micro inverters. Micro inverters are typically a little more expensive but are also more efficient. Clayco Electric installs both types of inverters but recommends the micros as they are less problematic. If you lose one micro you only lose one panel, versus losing the whole string if your string inverter is having issues. Clayco Electric can assist you with replacing your inverter if it has gone bad, or if you are just looking to upgrade your system.
