Here are the specifications of three models of Homage Inverters, Vision 500, Vision 1000 and Vision 2000, and common problems with solutions.
Problems & Solutions:
Solution for some other problems related to Homage Power Inverters:
1- UPS is running continuously in inverter mode despite of main electricity presence.
Sol: Make sure that input plug is connected and providing electricity to the UPS. Sometimes, fuses of input melt resulting in no input. You need to change the fuses. If you can not do it yourself, take it to the service centre. It also happens that if input voltage is too low to be acceptable, UPS does not switch over to main electricity supply. Check to make sure that that is not the case. If that is true, choose wide range from UPS for input. Note that choosing wide range increases the switch over time of UPS. You may also install a stabilizer to fix the voltage issue.
2- Batteries are connected properly but not getting charged. Electricity is also available.
Sol: Check to make sure that battery terminals are rust free. If they are rusty, electricity won’t flow through them. Clean them or change them if they are rotted due to corrosion. If rectifiers or step down transformer of charger are burnt, batteries will not be charged. You need to get your UPS repaired. Usually, it happens only if cooling fan of UPS was not working properly or UPS is placed at extremely hot place. Quality of internal circuitry also matters.
3- Batteries are charged but UPS is not providing any backup. In fact, UPS is not switching to backup mode.
Sol: Usually it happens if battery terminals are corroded. UPS can not draw enough current through them to provide the backup. You need to clean or change the battery terminals. Also check to make sure that output of UPS is properly connected. If everything looks fine from the outside, then problem could be inside of power inverter.
4- Everything seems fine but UPS is still not working. Batteries and wiring are also okay.
Sol: In that case, UPS might be faulty. You need to take it to the service centre. Note that, if UPS is filled with dust, that might also be responsible for the problem. If fan of UPS is stuck due to the mud inside it, UPS will not work either. Clean your UPS with a wind blower.
