INVO SERIES INVERTER/CHARGER
INSTALLATION & OPERATING MANUAL
8. No terminals or lugs are required for hook-up of the AC wiring. AC wiring must be no less than
10 AWG gauge copper wire and rated for 75oC or higher. Battery cables must be rated for 75oC or
higher and should be no less than as stated in table 1. Crimped and sealed copper ring terminal
lugs with a 5/16 hole should be used to connect the battery cables to the DC terminals of the
inverter/charger. Soldered cable lugs are also acceptable.
9. Be extra cautious when working with metal tools on, or around batteries. The potential exists to
drop a tool and short-circuit the batteries or other electrical parts resulting in sparks that could
cause an explosion.
10. No AC or DC disconnects are provided as an integral part of this inverter/charger. Both AC and
DC disconnects must be provided as part of the system installation. See INSTALLATION section
of this manual.
11. No over current protection for the battery supply is provided as an integral part of this
inverter/charger. Over current protection of the battery cables must be provided as part of the
system installation. See INSTALLATION section of this manual.
12. GROUNDING INSTRUCTIONS - This inverter/charger should be connected to a grounded
permanent wiring system. For most installations, the Ground Lug should be bonded to the
grounding system at ONLY one in the system. All installations should comply with all national
and local codes and ordinances.
Personal Precautions
1. Someone should be within range of your voice to come to your aid when you work near batteries.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3. Wear complete eye protection and clothing protection. Avoid touching eyes while working near
batteries. Wash your hands when done.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters
eyes, immediately flood eyes with running cool water for at least 15 minutes and get medical
attention immediately.
5. Baking soda neutralises lead acid battery electrolyte. Keep a supply on hand in the area of the
batteries.
6. NEVER smoke or allow a spark or flame in the vicinity of a battery or generator.
7. Be extra cautious when working with metal tools on and around batteries. The potential exists to
short-circuit the batteries or other electrical parts which may result in a spark that could in turn
cause an explosion.
Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
battery. A battery can produce short-circuit currents high enough to weld a ring or the like to metal,
causing severe burns.
If a remote or automatic generator start system is used, disable the automatic starting circuit and/or
disconnect the generator from its starting battery while servicing to prevent accidental starting during
servicing.

INVO SERIES INVERTER/CHARGER
INSTALLATION & OPERATING MANUAL
The Invo Series 5KVA Inverter/Charger can feed almost any kind of appliance including those with
motor characteristic, e.g. fluorescent lights, fans, refrigerators and air conditioners.
Note: Appliances such as air conditioners often require at least 3 minutes to restart after a short-term
power outage (time is required to balance the refrigerant gas in inside circuit). In order to protect your air
conditioner, please consult the manufacturer whether they have already provided a time delay function
before installing the INVO Series inverter; otherwise, the inverter will trigger an overload fault and shut
off its output to protect your appliance. Even so there is some risk of damage to the air conditioner for
which UNIPOWER cannot be held responsible.
Batteries
The INVO inverter/charger supports either a 48 volt or a 96 volt battery bank depending on the model.
Please refer to figure 2 for wiring the battery correctly. Before proceeding, ensure you have appropriate
size batteries for your application. The INVO inverter/charger can be used with flooded lead-acid, or
sealed GEL/AGM lead-acid batteries so ensure that your batteries are in one of these categories.
The battery must be wired to match the inverter/chargers DC input voltage specifications. We recommend that the
battery capacity not smaller than 100AH (INVC4850H) / 50AH (INVC9650H).

DC Disconnect and Over-Current Protection
For safety and to comply with regulations, battery over-current protection and disconnect devices are
required. Fuses and disconnects must be sized to protect the DC cable size used, and must be rated for DC
operation. Do not use devices rated only for AC service – they will not function properly.
Note that some installation requirements may not require a disconnect device, although over-current
protection is still required.
Battery Cable Connection
Observe Battery Polarity! Place the ring terminal of the DC cable over the bolt and directly against the
inverter/charger’s battery terminal. Tighten the M8 screw to 5-8 Nm. Do not place anything between
the flat part of the Backup terminal and the battery cable ring terminal or overheating may occur.
DO NOT APPLY ANY TYPE OF ANTI-OXIDANT PASTE TO TERMINALS UNTIL AFTER
THE BATTERY CABLE WIRING IS TORQUED!!
Figure 3 below illustrates the proper method to connect the battery cables to the inverter/charger
terminals.
WARNING: Shock Hazard. Installation must be performed with care for the high battery
voltage in series.
Caution!! Do NOT place anything between battery cable ring terminals and terminals on
the inverter. The terminal screw is not designed to carry current.
Apply Anti-oxidant paste AFTER terminals have been tightened.
Verify that the cable lugs are flush with the battery terminals.
Tighten battery cables to terminals (10~15 Nm).

AC Connections
Installation should be done only by a qualified electrician. Consult the local codes for the proper wire
sizes, connectors and conduit requirements.
On the left of rear chassis is the AC hardwire cover. A six-way terminal block is provided to make the AC
connections. The terminal block is used to hardwire the AC input, AC output, and ground. The National
Electrical Code requires that an external disconnect switch be used in the AC input wiring circuit. The
AC breakers in a sub panel will meet this requirement.
1. Disconnect the inverter/charger from the battery either by turning off the battery switch or
removing the battery cables from the battery. Turning off the inverter/charger does not constitute
disconnecting from the battery.
2. Feed the wires through the cable clamp and AC cover. See Figure 4.
Figure 4 - AC Cable Connections to inverter/charger
3. Following the wiring guide located in the AC wiring compartment as Figure 4, connect the GND
(green/yellow), Line (brown), and neutral (blue) wires from the AC input (utility, generator, etc.)
to the terminal block.
Caution!! Be sure that AC source is disconnected before attempting to hardwire it to the
inverter/charger.


Load indicator
The load indicator shows the load percentage in VA or W, whichever is bigger, the overload indicator will
flash when an overload is present.
Battery Charger

Inverter to Charger Transition
The internal battery charger and automatic transfer relay allow the inverter/charger to operate as
either a battery charger or an inverter (but not both at the same time). The inverter/charger
automatically becomes a battery charger whenever AC power is supplied to its AC input. The AC
input is internally connected to the AC output while in battery charger mode.

Charger Terminology
1. Constant Current Stage - During this cycle, the batteries are charged at a constant current.
2. Constant Voltage Stage - During this cycle, the batteries are held at a constant voltage (14.1V
per 12V block for AGM & GEL, 14.6V per 12V block for FLOODED) and accept whatever
current (less than the current in CC stage) is required to maintain this voltage. This ensures full
charging.
3. Float Stage - During this cycle, the batteries are held at the float voltage (13.5V per 12V block).
4. Whenever the AC is reconnected, the charger will reset the above cycle.
5. If the charger maintains the float state for 21 consecutive days, the charger will reset the cycle.
Circuit Breaker
The inverter/charger contains one input circuit breaker located on the rear panel of the chassis, next to the
AC input terminal block. This circuit breaker protects the charger and bypass circuits. The circuit breaker
will trigger if the input is over-current. The circuit breaker is push to reset.
