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 terminal 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 terminal overheating during periods of high
current draw. Use a stiff wire brush and remove all dirt and corrosion from the battery terminals and cables.
Note: for lead acid battery, the recommended charge current is 0.2C(C-battery capacity)
Please follow below steps to implement battery connection:
Assemble battery ring terminal based on recommended battery cable and terminal size.
Connect all battery packs as units requires. It is suggested to connect at least 200AH capacity battery for
5kva inverter.
Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are
tightened with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly
connected and ring terminals are tightly screwed to the battery terminals.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTION!! Do not place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are connected
tightly.
CAUTION!! Before making the final DC connection or closing DC breaker/disconnector, be sure
positive (+) must be connected to positive (+) and negative (-) must be connected to negative
(-).
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 requested to install a separate DC
over-current protector or disconnect device between battery and inverter. It may not be requested to have a
disconnect device in some applications, however, it’s still requested to have over-current protection installed.
Please refer to typical amperage in below table as required fuse or breaker size.
Over torqueing may cause the bolt to break.
Equipment Damage
The inverter is not reverse polarity protected. Reversing the battery polarity on the DC
