  • Are you in the dark during load shedding?
  • Does your favourite program stop recording on your PVR?
  • Do you need to catch up work on your computer?
  • Does your phone run flat when you need it the most?

You need an inverter system. See below Frequently Asked Questions on how they work:

Q) What is an inverter system and what does it do do?
It is an inverter unit coupled with a battery which provides power when there is load shedding. It keeps its battery charged when there is Eskom power. As soon as Eskom power cuts, the system instantly transfers over to battery power so you can keep your lights, TV, computers (excluding Apple Mac Desktops only), chargers and wifi running during load shedding.

Q) Is it easy to connect up? Do I have to fiddle with electronics?
It is super easy The system is plug and play.
The inverter has a regular 3 pin plug that goes into the wall. You then have a 3 way multiplug on the inverter that allows you to connect any appliance you want. Keep the appliances connected at all times, the inverter will automatically switch to battery as soon as it detects Eskom power is down.

Q) How much backup time will I have on the unit before normal Eskom power come back on to recharge the battery?
Assume a computer, TV, and desk lamp are connected to the inverter:
This unit will last 2-3 hours

Only want a lamp, wifi router and laptop connected to the inverter:
This unit will last 5-6 hours

Q) What appliances can I run on the inverter system?
Our plug and play systems will run any appliance that has low power usage and does not have a motor. So you can run TVs, computers, wifi, lights, chargers, etc. 
Fridges, fans, heaters are not recommended to be connected to inverters. For those items, we can suggest a more specialised system - please click "contact us" and let us know your requirements.

Please note, this unit is considered as a 'large' UPS - it will not be able to charge a smaller UPS as it is modified sine wave

Q) What is the warranty/guarantee?

The entire system comes with a full 1 year warranty.

*PLEASE NOTE- If COLLECTION is selected, there is no additional charge, but unit will not come with pallet packaging for couriers

Here’s how to maximize your inverter’s battery life

● Please leave your inverter kit plugged in and turned on. It will keep your batteries at constant full charge – this is the best state to keep them in.

● If there is no load shedding, after a few weeks, the acid will start to sulphate on the top of the battery, so please do the following: Once every 1-2 months, please unplug the inverter from the wall and let it run until the inverter starts beeping, then immediately plug it back in. This will circulate the acid and will tremendously increase the cycle life of your batteries.

Please note:

White polystyrene is there to keep the batteries from moving around, it does not have to be removed and is 100% safe!

  • Asked by Andre
    Does this unit have AVR as well? Can you run this as a UPS permanently connected to your computer? Answer:
    Yes, it does have a built-in AVR and switch over. Yes, they will work as a UPS for a computer, and will keep the average computer running for more than 4 hours.
  • Asked by Juan
    If you use this inverter & battery instead of an ups, does it constantly draw power from the battery or bypasses the battery untill the power is cut, also does it have overcharging protection? Answer:
    It bypasses when the batteries are fully charged. It uses around 10W just to keep the batteries at float charge. Yes, it keeps them at floating charge so will not overcharge them.

    Can I use this product using solar panels Answer:
    Yes, you would need to add this: <a href=""></a>
  • Asked by Riaan Joubert
    My dad requires oxygen supplied by an oxygen concentrator. I assume it has motor and would not be able to use the Mecer Inverter. WIth load shedding he has to switch to an oxygen sillinder that provides 4 to 8 hours of backup oxygen. What system would be ideal for backup for the concentrator? Answer:
    Does the oxygen concentrator have a plug that converts to DC voltage (like AC220V to DC12V or DV24V for example?). If it does, then there is no issue using this MEcer inverter with it.
  • Asked by Adriano Frittella
    Does the on/off switch work with the Mecer 1200VA inverter plugged into supply? Answer:
    The on/off switch will only control whether it comes on when it is in battery mode. When it is plugged into the wall and there is power, it will go into bypass mode whether the switch is pressed in or out
