Why Your Inverter Isn't Switching Over Wiring, transfer mode, battery cut-off: why backup fails at the moment you need it. The fix is usually simpler than the stress of living with the problem. Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Only circuits wired to the inverter output get backup. - Bypass mode passes grid power straight through with no backup. - Low-battery cut-off stops backup early. Quick answer If everything goes off in a blackout, either the circuit isn't wired through the inverter output, the inverter is in bypass, or the battery has hit its low cut-off. If computers restart on changeover, the inverter is in a slow transfer mode (APL/appliance) instead of UPS mode, or it's too slow for sensitive equipment. Check the mode and which circuits are on the inverter output.

Real products, live prices, in stock now ## Key takeaways - Only circuits wired to the inverter output get backup. - Bypass mode passes grid power straight through with no backup. - Low-battery cut-off stops backup early. - Use UPS mode for computers and networks. - Servers and network racks may need a true online UPS. ## Quick checks you can do first 1. **Check which sockets have backup**: Test with the main breaker off. Sockets that go dead aren't on the inverter output. 2. **Check the mode**: Set UPS mode (fast transfer) if computers restart during changeover. 3. **Check the bypass switch**: A manual bypass left on means no backup. 4. **Check battery level**: If the battery is already low, the inverter shuts down instead of switching. 5. **Test it**: Switch off the incoming supply at the breaker and watch what stays on. **Important**: Switch off and isolate power before opening any equipment. Batteries, inverters and mains wiring can cause serious injury; leave internal work to a qualified technician. ## What usually causes it | Symptom | Likely cause | Fix | | --- | --- | --- | | Whole house goes dark | Circuits not on inverter output | Rewire essential circuits | | Computers restart on changeover | APL mode or slow transfer | UPS mode or online UPS | | Nothing switches, display normal | Bypass switch on | Return to inverter mode | | Switches then dies quickly | Battery low or weak | Charge/test batteries | | Works sometimes | Loose connection or faulty relay | Technician check | ## When to call a technician - Circuits need rewiring to the inverter output. - Computers or servers drop on every outage. - The inverter clicks but doesn't switch. - You need a changeover switch or distribution board work. **When to call a professional**: Qyvea technicians diagnose and fix this on site across Nairobi and Kenya. Call [0113 301 244](tel:+254113301244) or [WhatsApp a technician](https://wa.me/254113301244?text=Hi%20Qyvea%2C%20I%20need%20a%20technician%20for%20inverter%20changeover). Running this across several sites or branches? A [Qyvea maintenance contract](https://qyvea.co.ke/maintenance-contracts-for-business-kenya) catches these faults on scheduled visits, with a written report after each one. ## Parts that fix it ## Frequently asked questions Why do my computers restart when power goes even with an inverter? Many inverters take 10–20 ms to switch, which some PCs can't ride through. Use UPS mode or an online UPS for computers. Can an electrician add more circuits to my inverter? Yes, as long as the inverter can carry the extra load. We check the sizing first. What is bypass mode? A setting or switch that feeds the house straight from the grid, used for maintenance. In bypass there is no backup. ## Why customers choose Qyvea **Genuine brands**: Manufacturer warranty on what we sell, so you are not gambling on the box. **One team, start to finish**: The people who advise you also install and support it. **Fast answers**: WhatsApp replies usually within 30 minutes, and delivery within 24 hours in Nairobi. **Easy to buy**: Pay by M-Pesa, bank transfer or card.
