Product Introduction
Felicity Solar IVGM4648/5048 is a multifunctional inverter, combining
functions of inverter, solar charger and battery charger to offer
uninterruptible power support with portable size. Its comprehensive LCD
display offers user configurable and easy accessible button operation such as
battery charging, AC/solar charging, and acceptable input voltage based on
different applications.
2.1 Operation
Modes
IVGM system normally has the following operation modes based on your
configuration and layout conditions.
Mode 1: The energy produced by the PV system is used to optimize self-
consumption. The excess energy is used to recharge the batteries, the rest is
exported to grid. Mode 2: When there is no PV, and the battery is sufficient,
it can supply the load together with grid power. Mode 3: When grid fails, the
system automatically switches to Back-Up mode. The Back-Up can be supported by
pv and battery. Mode 4:There is no PV, the battery is low, and the battery is
charged through the grid.

- Install in a well-ventilated place
- No flammable or explosive materials close to inverter
- The AC overvoltage category of inverter is category III
- Maximum altitude: 2000m
Inverter cannot be installed near flammable, explosive or strong
electromagnetic equipment. Ensure there is sufficient space for heat-
releasing. Generally, space requirement should be met as below:
Table 3-3-1 Detailed installation space
| Minimum clearance
---|---
Lateral| 200mm
Top| 450mm
Bottom| 450mm
*Do not open the
cover of the inverter or replace any part as incomplete inverter may cause
electric shock and damage the device during operation.
The installation of inverter should be protected under shelter from direct
sunlight or badweather like snow,rain, lightning etc. 
3.4 Mounting
The inverter is heavy, please be careful when removing it from the package.
The inverter is suitable for mounting on concrete or other non-combustible
surface only. Step 1. Please use the mounting bracket as a template to drill 5
holes in the right positions (10mm in diameter, and 80mm in depth). Use M8
expansion bolts in accessory box and fix the mounting With a 12mm drill
bracket onto the wall tightly. The installation of inverter support is shown
in Figure 3.4-1.Step 2.
Lift the inverter to fix it on the installation bracket, We can prevent theft
by locking. See Figure 3.4-2.
NOTE *Be careful when mounting because the inverter is very heavy.
Electrical Connection
- High voltages in power conversion circuits. Lethal hazard of electric shock or serious burns.
- All work on the PV modules, inverters, and battery systems must be carried out by qualified personnel only.
- Wear rubber gloves and protective clothing (protective glasses and boots) when working on high voltage/high current systems such as INVERTER and battery systems.
4.1 PV Connection
Before connecting PV panels/strings , please make sure requirements are
followed as below:
- The total short-circuit current of PV string must not exceed inverter’s max DC current.
- The minimum isolation resistance to ground of the PV string must exceed 19.33kQ in case of any shock hazard.
- PV string could not connect to earth/grounding conductor.
- Use the right PV plugs in the accessory box.
| Wire Size | Cable(mm) |
|---|---|
| 12AWG | 7 |
Step 1. Prepare PV positive and negative power cables Step 2. Connect PV cables to PV connectors. See Figure 4.1-2.
NOTE
- PV cables must be tightly crimped into the connectors.
- For Amphenol connector, the limit buckle cannot be pressed.
- There will be a “click “sound if connectors are inserted correctly into PV plugs.
Step 3. Screw the cap on and plug it onto inverter side. There will be a click
sound if connectors are inserted correctly into PV plugs.See Figure 4.1-3.
The polarity of PV
strings cannot be connected reversely, otherwise the inverter could be
damaged.
4.2 Battery Connection
Please be careful about any electric shock or chemical hazard. Make sure there
is an external DC breaker (125A) connected to the battery without build-in DC
breaker.
The polarity of battery cannot be connected reversely, otherwise the inverter
could be damaged.
| Wire Size | Cable(mm) |
|---|---|
| 1/0AWG | 25 |
Step 1. Prepare battery cables and accessories, and route the battery power
cable through the battery cover. Use accessories box accessories, battery
power cable 20-35mmz2. Step 2. Make battery terminals , Strip cable coat,
revealing 10mm length of metal core.Use special crimper to compress battery
terminal tightly. Step 3. Connect the battery terminal to the inverter. Ensure
that the battery polarity is connected correctly. 4.3 On-Grid & Back-Up
Connection
An external AC breaker is needed for on-grid connection to isolate from grid
when necessary. The requirements of on-grid AC breaker are shown as below.
Don’t connect the PE
wire wrong.
Table 4.3-1 : Recommended table of AC circuit breakers
| INVERTER MODEL | AC BREAKER SPECIFIFICATION |
|---|---|
| IVGM4648/5048 | 40A/230V,2P |
Note
The absence of AC breaker on back-up side will lead to inverter damage if
an Se electrical short circuit happens on back-up side.
- 0n the AC side, the individual breaker should be connected between inverter and Grid but before loads. See Figure 4.3-2.
- Make sure the inverter is totally isolated from any DC or AC power before connecting AC cable.
Step 1. Prepare the terminals and AC cables as below. See Figure 4.3-3. Table 4.3-2 : Ac cable specifications
| Grade | Description | Value |
|---|---|---|
| A | Outside diameter | 13-18 mm |
| 8 | Separated wire length | 20-25 mm |
| C | Conductor wire length | 7-9 mm |
| D | Conductor core section | 4-6 mm |
Step 2. Using the terminals in the accessory box, pass the AC cable through the terminal cover. See Figure 4.3-4.
Note
The absence of AC breaker on back-up side will lead to inverter damage if
an Be electrical short circuit happens on back-up side.
Step 4. Connect the combined AC cable to the AC terminal of the inverter,
tighten the cable to a torque of 2.0 N.m to 2.5 N.m, and then lock the AC
cover.See Figure 4.3-6. 4.4 Smart Meter & CT Connection

4.6 DRMS Connection
DRMS(Demand response enabling device) is used for Australia and New Zealand
installation (also used as remote shutdown function in European countries), in
compliance with Australia and New Zealand safety requirements( or European
countries). Inverter integrates control logic and provides an interface for
DRMS. The DRMS is not provided by inverter manufacturer. Detailed connection
of DRMS & Remote Shutdown are shown below:
Step 1. Screw this plate off from the inverter. See Figure 4.6-1. Step 2. Plug
out the RJ45 terminal and dismantle the resistor on it. Plug the resistor out,
leave the RJ45 terminal for next step. NOTE
- The R345 terminal in the inverter has the same function as DRED. Please leave it in the inverter if no external device is connected.
Step 3-1 Pass the RJ45 cable through the steel plate and connect the DRED cable to the RJ45 terminal. As shown in Figure 4.6-3, Table 4-9 describes the 6-pin port definition. Table 4.6-1 :Port pin allocation table
