more inverters. Current sharing between paralleled inverters is ±10%.
13.2
Alternatively, separate sources may be used for the inputs to these inverters
while the outputs are connected in parallel. In either case, output loads
should have individual distribution circuit breakers. The following table shows
output current and total volt-amperes for inverters connected in parallel. As
mentioned earlier, INV5000-HS refers to both the 230VAC INV5000-HS-230
and two INV2500-HS inverters in an INVR2U-HS shelf producing 115VAC.
Table 13-1.
Output For Paralleled Inverters
13.3
Four INV2500-HS inverters in two INVR2U-HS shelves connected in parallel
could be used to produce 10 kilovolt-amperes of 115VAC or could also be
used as a 3+1 redundant inverter providing 7.5 kilovolt-amperes of 115VAC to
a load.
13.4
Figure 9 shows four INV2500-HS inverter modules in two INVR2U-HS
shelves connected in parallel to give 10KVA of AC output at 115VAC. The AC
output is distributed by a DPAC1UT AC Distribution Panel made by UNIP-
OWER Telecom. Note that only 115VAC inverters can be used with the
DPAC1UT distribution panel and not the 230VAC INV5000-HS-230. 230VAC
INV5000-HSs require breakers on both line sides, and this is not available
with the DPAC1UT. Note also that only the “T” (Terminal Strip) Option of the
DPAC1U can be used with these inverters and that, as shown in Figure 9,
the A side AC input terminals must be strapped in parallel, i.e., A1G to A2G,
A1N to A2N and A1L to A2L; in the same way, the B side AC input terminals
must also be strapped in parallel.

INSTALLATION AND TESTING
14.1
The inverter or inverters should be initially tested in their shelves. For 23-inch
rack mounting use panel extenders.
14.2
Put all input and output circuit breakers in the off (down) position. See Figure
3. Remove the rear plastic safety cover.
14.3
Connect the input battery to the -48VDC and 48VDC Return input bus bars
