We sell power backup solutions for your home or small office to help you avoid the frustration experienced when Kenya Power implements load shedding. Load shedding in Kenya has become a reality and it’s imperative to keep your life functioning during these times. Having a power backup solution means that you can continue to work and play during these times when most  feel frustrated.

We supply power backup systems that are portable or fully integrated into your DB board. Our range of backup power solutions can help you power your home or small office during those challenging load shedding hours and other unplanned power failures. Our systems are silent and environmentally friendly as they don’t need fuel.

The benefits of inverters for home power backup and small offices

There are several benefits for your home when using an inverter with batteries:

  • Portability. Some units have wheels. You can also take your inverter if you move to another home.
  • Installation is easier when compared to petrol generators.
  • Automatic failover when power in your home is lost. This gives you a reliable power supply.
  • Durable batteries for maximum battery life.
  • Silent operation. No noise from the motor.
  • No petrol fumes
  • No need to purchase petrol
  • Fast charging capability
  • Clean power that is safe for electronic devices. We only supply Pure Sine Wave inverters.
  • Inverter requires no maintenance.
  • Batteries can be easily replaced.

What appliances and devices can I run on a backup power system?

You can safely connect the following appliances as long as the total power consumption does not exceed the supply of the backup batteries.

  • LED lights
  • Wifi
  • Computers and printer
  • Fan
  • Garage door motor
  • TV and decoders
  • Fridge with deep freezer
  • Home alarm system
  • Intercom
  • Sound system

Other appliances? – You can connect more appliances if you add more batteries to your battery bank. Its recommended to avoid appliances with heating elements.

What is the difference between an Inverter Based system and a UPS system?

A UPS system is designed to backup sensitive equipment like servers, computers, medical equipment, telecommunications equipment, etc. Standard UPS systems have small internal battery sets and can only provide short backup times of approximately 5 – 10 minutes which cannot be extended as the internal battery chargers are small and can only cater for the internal battery sets they were designed for. Additional or external batteries cannot be connected to these UPS systems.

There are also long backup UPS systems available which can be supplied with external battery sets to provide backup for, usually not more than 2 hours. If the user requires longer backup than 2 hours, the system would then have to be intentionally oversized to cater for the longer backup time, which can then be extended to 4 – 6 hours. For longer backup times, UPS systems should be installed in conjunction with a generator.

The double conversion online UPS systems have no break whatsoever and the sensitive equipment will always run on electronically produced power and is not directly connected to the mains power.

In contrast, inverter based backup systems do have a small break when they switch over to backup power (irrespective of the inverter system brand or model). The higher quality systems, which Greenlog Solution supplies, switch over in a very short time and it is hardly noticeable. Inverter backup systems incorporate larger battery chargers which allows larger battery sets to be installed which results in much longer backup times than UPS systems.

In contrast, Inverter Based systems, which do have a small break when they switch over to backup power (irrespective if the inverter system, but the good quality systems have a power break during switchover which is hardly noticeable), incorporate large battery chargers which enables extra large battery sets to be installed, which results in extra long back-up times.This is not possible with UPS systems.

How long will the inverter system run when there is a power failure?

The amount of backup time is determined by the size of the connected battery bank and the load drawn from the system. The backup time is directly in proportion to the load drawn. The backup time is normally calculated at full load (i.e. if the system is a 2200VA system, full load is 2200VA). If you remove some of the connected load, then the backup time will be extended accordingly.

How long does it take to charge the batteries when utility power returns?

The recharge time of the batteries depends on how much power was removed from the batteries during a power failure in Kenya. The recharge times in the catalogues is indicated at full battery discharge.

If there is a planned power outage, can the system last for the full power outage time?

Yes, but the system has to be correctly sized to begin with. These systems are capable of bridging power outages from 2 – 24 hours or (e.g. for 2 hours per day twice a day) as the battery chargers are powerful enough to recharge the battery bank to cater for the second outage on the same day (providing there is enough time between the 2 outages – at least 4-6 hours). Again this process if fully automatic.


These systems require minimum maintenance. Depending on the system chosen, the batteries are either semi sealed lead calcium batteries or fully sealed Gel batteries. Batteries are maintenance free and do not have to be filled. It is recommended that battery sets are installed in a battery cabinet and are locked in a room with ventilation, where small children do not have access. As with all batteries, these batteries can be dangerous if tampered with. Greenlog Solutions does supply complete systems with batteries and battery cabinets in Kenya.
