The GES-UPS-One is ideal for backup applications
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 |
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.

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.
There are 4 ways to determine the energy usage of an appliance.
This PDF file lists the most common appliances and will give you an indication of typical energy ratings. Click here to download the PDF file, GES appliances, typical energy usage
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.
