What do solar inverters do?
09/22/2021, 10:19
The main purpose of inverters is to convert direct current (DC) electricity into altering current (AC) electricity which is used to power most appliances.
How do you maintain an inverter?

It is recommended to wipe down your inverter when it gets dusty and to change the air intake filters, but it is best to call a technician if you are unsure of your skills.
Where should I install my inverter?

Solar inverters best operate in shaded cool areas and are sensitive to overheating, so we recommend keeping them away from sunlight.
