Installation

Wall mounted

Consider the following points before selecting where to install:

 Do not mount the inverter on flammable construction materials.  Mount on a solid surface  Install this inverter at eye level in order to allow the LCD display to be read at all times.  The ambient temperature should be between 0°C and 55°C to ensure optimal operation.  The

recommended installation position is to be adhered to the wall vertically.

 For proper air circulation to dissipate heat, allow a clearance of approx. 20 cm to the side and approx. 50

cm above and below the unit.

SUITABLE FOR MOUNTING ON CONCRETE OR OTHER NON-COMBUSTIBLE SURFACE ONLY.

Please follow the steps as below to finish the installation.

Employ the mounting plate as a template for marking the

positions of the boreholes. Mount the mounting plate with

supplied screws to fix the plate in place.

Insert two screws to the two sides of inverter as showed in the

figure. Please don’t screw them tightly at this time. Then, place

the inverter onto the mounting plate and fix two screws tightly.

Then, insert the other two screws on the two sides of inverter

as showed in the figure and fix them tightly.

For proper air circulation to dissipate heat, please keep the

space around the inverter more than 20 cm.

Desktop

The inverter can be switched to desktop form factor by following the below steps:

FlinSlim Edge Solar Hybrid Inverter with In-Built Stabilizer

Take off the LCD panel by removing screws.

Remove the metal case showed in the figure.

Place the metal case to the position where the LCD panel was

previously removed and fix it with screws.

Place the LCD panel to the position where the metal case was

previously removed and fix it with two screws.

Place the inverter in a protected area that is free of excessive

dust and has adequate air flow. Please place the inverter away

from other units at least 20 cm to avoid interference.

Battery Connection

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.

2. 3KVA model supports 24VDC system and 5KVA model supports 48VDC system. Connect all battery packs

as below chart. It’s suggested to connect at least 100Ah capacity battery for 3KVA model and at least

200Ah capacity battery for 5KVA model.

WARNING: Shock Hazard

Installation must be performed with care due to high battery voltage in series.

3. Insert

the ring terminal

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

(-).

AC Input/Output Connection

CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between

inverter and AC input power source. This will ensure the inverter can be securely disconnected during

maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 30A

for 3KVA and 50A for 5KVA.

CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input

and output connectors.

WARNING!! When using sockets as the output, please make sure that the current of each socket is less than

10A, in case of electric hazard.

WARNING! All wiring must be performed by qualified person.

WARNING! It's very important for system safety and efficient operation to use appropriate cable for AC input

connection. To reduce risk of injury, please use the proper recommended cable size as below.

Please follow below steps to implement AC input/output connection:

1. Before making AC input/output connection, be sure to open DC protector or disconnect first.

2. Remove insulation sleeve 10mm for six conductors.

3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws.

Be sure to connect PE protective conductor ( ) first.

5. Make sure the wires are securely connected.

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 manufacturer

of air conditioner if it’s equipped with time-delay function before installation. Otherwise, this inverter/charger will

trig overload fault and cut off output to protect your appliance but sometimes it still causes internal damage to the

air conditioner.

PV Connection

CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter

and PV modules.

WARNING! All wiring must be performed by a qualified personnel. WARNING! It's very important for system safety and efficient operation to use appropriate cable for PV module

connection. To reduce risk of injury, please use the proper recommended cable size as below.

PV Module Selection:

When selecting proper PV modules, please be sure to consider below parameters:

1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.

2. Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.

Note: * Vmp: panel max power point voltage.

The PV charging efficiency is maximized while PV system voltage is close to Best Vmp.

Maximum PV module numbers in Series: Vmpp of PV module * X pcs ≒ Best Vmp of Inverter or Vmp

range

PV module numbers in Parallel: Max. charging current of inverter / Impp

Total PV module numbers = maximum PV module numbers in series * PV module numbers in parallel

Take 5K W/O MPPT model inverter as an example to select proper PV module. After considering Voc of PV module not exceed 105Vdc and max. Vmpp of PV module close to 60Vdc or within 56Vdc ~ 72Vdc, we can choose PV module with below specification.
