INVO SERIES INVERTER/CHARGER
INSTALLATION & OPERATING MANUAL
Manual No. INVO-1 Page 7 08/11 invo-man
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).
