SolaX Solar Inverter is a hybrid inverter that allows you to use your solar power at night after you charge your battery. It also directs power to any appliances operating throughout the day while storing unused power in the battery. You can also monitor its real-time performance through your iPhone or Android phone with the SolarMAN app.
But in case you see any issue, we have put together a list of faults and solutions from the users manual so you can work on your SolaX Solar Inverter. The list contains procedures for solving possible problems with the X-hybrid series inverters, and provides you with troubleshooting tips.
Should you decide to follow the recommended actions, please note that safety measures should be observed to avoid any risk of injury. Otherwise, contact a qualified electrician for assistance.

If you need the full information on this, you can find them on the SolaX solar inverter manual’s Troubleshooting section. Should you follow the troubleshooting steps above but the issue is not fixed on your SolaX solar inverter check if it’s still within the warranty period so you can contact the equipment installer or supplier.
If your SolaX Solar Inverter is outside the warranty period we suggest that you contact a professional solar power expert. If you’re in the Gold Coast or Brisbane area contact Gold Coast Power Solutions here and we will be in touch to provide you with further assistance.
