Frequently Asked Questions for this UPS

What is the available, usable energy storage?
The deep cycle batteries can be discharged up to 80% depth of discharge. So the available usable energy will be as follow:

Number of batteries Energy in Ah
(Ampere hours)
Energy in Ah
(Ampere hours)
(at 80% DoD)
Energy in Wh (Watt-hours)
(at 80% DoD)
One battery 100 Ah 80 Ah 960 Wh
Two batteries 200 Ah 160 Ah 1920 Wh

 

How long will the battery last? / How much backup time will I have?
It depends on how much power is drawn from the UPS. The following table will illustrate available backup time depending on power drawn.

One battery

Power at 100% Load Power at 75% Load Power at 50% Load Power at 25% Load
Power 720 W 540 W 360 W 180 W
Backup time 1 h, 20 m 1 h, 46 m 2 h, 40 m 5 h, 20 m

Two batteries

Power at 100% Load Power at 75% Load Power at 50% Load Power at 25% Load
Power 720 W 540 W 360 W 180 W
Backup time 2 h, 40 m 3 h, 33 m 5 h, 20 m 10 h, 40 m

 

What is the charge time if the battery is empty?

The charge rate of the build-in charger is 20A. So if the inverter shut down as it is programmed to do at 80% Depth of Discharge of the batteries, then the time required to fully recharge the batteries will be as follows:

Number of batteries Energy in Ah
(Ampere hours)
Energy in Ah
(Ampere hours)
(at 80% DoD)
Charge time
One battery 100 Ah 80 Ah 4 h
Two batteries 200 Ah 160 Ah 8 h

 

Frequently Asked Questions for UPSes in general

What is the difference between an UPS and a backup system?

An UPS supplies backup power and a backup power system can function as an UPS. But there are some key differences in functionality and what we define as a Backup system and as an UPS.

UPS Systems Backup power systems
  • Is typically small and portable in an enclosure.
  • Supplies power at one point through a multi-plug to certain devices.
  • Is not compatible with solar power.
  • Is limited to the amount of power can supplies, typically less than 3 kW.
  • Is permanently installed.
  • Is typically integrated into a buildings distribution board and provide backup power to certain circuits.
  • It is compatible with solar power and can intelligently manage the flow of energy between solar panels, batteries and a grid.
  • It’s not that limited to the amount of power can supply, one inverter can supply up to 15 kW.
  • How does one calculate what size UPS system one needs?

    One needs to calculate the total power consumption of all the devices together that you would like to run from the UPS.
    There are basically two ways to calculate the power and energy requirements of a UPS system.

    1. Install an energy logging device, this device will tell you the peak amount of power drawn at once, and the total energy consumed per day and per month. These devices are widely available to buy online, one good example is the Efergy Energy Logger.  https://greenenergysolutions.co.za/energy-meters/
    2. Download and complete our “Energy Usage Calculator” This can be completed and emailed back to us. Click here to download our “Energy Usage Calculator.

    How do I determine the energy usage of a specific appliance?

    There are 4 ways to determine the energy usage of an appliance.

    • Look at the nameplate on the appliance
    • Lookup the applicant model number on the manufacturer’s website.
    • Lookup the energy usage in the manual that came with the appliance.
    • Measure it with an energy meter or current meter.

    Can I add solar panels to these UPS systems.

    Technically yes, but it is not recommended. To effectively make use of power generated by solar panels, the energy must be stored in the batteries during the day, and used at times when the sun is not shining. So the batteries need to be “cycled” each day. To make these UPS systems cost-effective, batteries are used that have up to 300 cycles. For solar application, one would typically use more expensive batteries with one thousand cycles or more at least. Lithium-Ion batteries can have up to 5000 cycles.
