UPS2000-G-(6 kVA-20 kVA)
User Manual

The UPS2000-G-6 kVA/10 kVA parallel system cannot shares a battery string.

If a UPS2000-G-15 kVA/20 kVA parallel system shares a battery string, set the same
battery string capacity and charge current for each UPS.

Battery capacity (Ah) = Capacity of a single battery string x Number of parallel battery
strings/Number of parallel UPSs sharing a battery string. Maximum charge current (Ah) =
0.1 x Capacity of a single battery string x Number of parallel battery strings/Number of
parallel UPSs sharing a battery string. If the calculated maximum charge current is greater
than 4 A, set it 4 A. Use two UPSs sharing a 65 Ah battery string as an example: If the
calculated battery capacity is 65 x 1/2 = 32.5, set it to 32 Ah; if the calculated maximum
current is 0.1 x 65 x 1/2 = 3.25, set it to 3.0 A.

If a single 15 kVA/20 kVA UPS connects to two battery packs, the maximum charge
current must be less than or equal to 2.0 A.

Number of batteries/Positive batteries and Negative batteries parameters
−
Set the number of batteries. The value ranges from 16 to 20. The default value is 20.
When the number of batteries N is less than 20, the system output power is derated
to N/20 in battery mode. The parameter is configurable in non-battery mode or
non-battery ECO mode. You need to set Number of batteries on the UPS2000-G-6
kVA/10 kVA, and set two battery strings (positive and negative) on the
UPS2000-G-15 kVA/20 kVA.
− Battery capacity parameter
Set the battery string capacity. The value ranges from 7 Ah to 1000 Ah. For the
UPS2000-G-6 kVA, the default value is 7 Ah on a standard model and 40 Ah on a
long backup time model; for the UPS2000-G-10 kVA, the default value is 9 Ah on a
standard model and 65 Ah on a long backup time model; for the UPS2000-G-15
kVA/20 kVA, the default value is 65 Ah on a long backup time model. Battery
capacity is the sum of all battery capacities, set the parameters based on the actual
battery capacity. The parameter is configurable in non-battery mode or non-battery
ECO mode.
− Intelli. Hibernation
This parameter is set to disabled by default. When it is set to enabled, the intelligent
battery hibernation function is enabled. The parameter is configurable in any mode.
− Overtemp. thres. parameter
Set an alarm threshold for high battery temperatures. The value ranges from 45º C to
55º C. The default value is 50º C. The parameter is configurable in any mode.
− Undertemp. thres. parameter
Set an alarm threshold for low battery temperatures. The value ranges from –30º C
to +5º C. The default value is –5º C. The parameter is configurable in any mode.
