Use screws, bolts, or other mounting hardware of sufficient strength and length to secure the unit to the
mounting surface.
3.3 Battery Wiring
Before connecting the batteries, please take off the DC and AC terminal covers by removing their screws.
DC terminal bolt size: M8.
Keep the battery bank as close as possible to the inverter.
Follow the suggested cable length in the table below.

Please follow the above minimum wire size requirement.
One cable from the battery to the inverter is always best. If you can’t use one cable of sufficient length,
you may use two cables so long as the square area of both cables adds up to the recommended square of the
minimum wire gauge. For example, one cable of 100mm
2
can be replaced by two cables of 50mm
2
to
obtain the recommended wire gauge. When in doubt, round up and keep the cable length as short as
possible.
Battery cables must have crimped (or preferably,
soldered and crimped) copper compression lugs
unless aluminum mechanical lugs are used. Soldered
connections alone are not acceptable. High quality,
UL-listed battery cables are available. These cables
are color-coded with pressure crimped, sealed ring
terminals.
Battery terminals must be clean to reduce the
resistance between the DC terminal and cable
connection. A buildup of dirt or oxidation may
eventually lead to the cable and / or the terminal overheating during periods of high current draw. Use a stiff
wire brush to remove all dirt and corrosion from the battery terminals and cables.
Reducing RF interference
To reduce the effect of radiated interference, twist the DC cables. To further reduce RF interference, shield
the cables with sheathing /copper foil / braiding.
Taping battery cables together to reduce inductance
Do not keep the battery cables far apart. In case it is not convenient to twist the cables, keep them taped
together to reduce their inductance. Reduced inductance of the battery cables helps to reduce induced
voltages. This reduces ripple in the battery cables and improves performance and efficiency.
CAUTION: For safety operation and regulation compliance, it’s required to install a separate DC
over-current protector or disconnect device between battery and inverter. It may not be required to have a
