1 Connect Ground wire to Ground terminal.
2 Connect AC input Hot1 to Input Hot.
3 Connect AC input Hot2 to Input Neutral.
4 Connect Output Hot to AC output Hot1.
5 Connect output Neutral to AC output Hot2.
6 DON’T CONNECT AC INPUT NEUTRAL or load neutral to the inverter.
NOTE: The M5000H-48BP can work with Sigineer Power transformer to split the 240Vac into 120/240Vac
voltages.
CAUTION: Important
Be sure to connect AC wires with correct polarity. If L and N wires are reverseed, it may cause utility
short-circuited when these inverters are worked in parallel operation.
CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s
required to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and
recovers in a short time, it will cause damage to your connected appliances. To prevent this kind of damage,
please check with manufacturer of air conditioner that if it’s equipped with time-delay function before
installation. Otherwise, this off grid solar inverter will trigger overload fault and cut off output to protect
your appliance but sometimes it still causes internal damage to the air conditioner.
Preventing Paralleling of the AC Output
The AC output of the unit should never be connected to the utility power / generator.
Such a connection may result in parallel operation of the different power sources and AC power from the
utility / generator will be fed back into the unit which will instantly damage the inverter and may also pose a
fire and safety hazard.
3.6 Communication With Lithium Batteries
The BMS port allows the M series inverters to communicate with lithium batteries BMS with the same
protocol. Our M series inverters support a growing number of lithium batteries from the big brands.
To get more details of our BMS protocol and the compatible lithium battery models, pls email us at
info@sigineer.com.
Please follow below steps to implement lithium battery connection:
Connect one end of RJ45 of battery to BMS communication port of inverter. Connect the other end of RJ45
cable to battery communication port.
