Battery Connection
Lead-acid Battery Connection
User can choose proper capacity lead acid battery with a nominal voltage at 48V. Also, you need to choose
battery type as “AGM(default) or FLD”
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.
O-type terminal:
WARNING! All wiring must be performed by a qualified person.
WARNING! It's very important for system safety and efficient operation to use
appropriate cable for battery connection. To reduce risk of injury, please use the
proper recommended cable and terminal size as below.
Recommended battery cable and terminal size:
Note: For lead acid battery, the recommended charge current is 0.2C(Cbattery capacity)
Please follow below steps to implement battery connection:
1.
Assemble battery ring terminal based on recommended battery cable and terminal size.
2.
Connect all battery packs as units requires. It’s suggested to connect at least 200Ah capacity battery for
SPF 6000 ES PLUS.
3.
Frist，pass the battery cable through the protective shell，and then insert the ring terminal of battery
cable flatly into battery connector of inverter and make sure the bolts are tightened with torque of 2Nm.
Make sure polarity at both the battery and the inverter/charge is correctly connected and ring terminals
are tightly screwed to the battery terminals.Last，insert the protective shell.
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
(-).
