Frequently Asked Questions

Do solar inverters go offline at night?

A solar inverter converts DC to AC, this means the appliances in the houses are provided normal current through the solar inverter. Thus, leaving the solar inverter on at night would not interrupt; settings of different devices (clocks, alarms, ovens etc.) If you plan to have continuous don’t set them to go offline.

How long does a solar inverter last?

The lifetime of a solar inverter mainly depends on the quality of inverter module, environment, and maintenance. The typical lifespan of an economical model is 10-12 years. These are some models that comes with up to 5 years warranty;

• Sunbridge 4000 Off-Grid
• Sofar Single Phase Dual MPPT Solar Inverter (5KTLM-G2)
