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.

Table 3-3-1 Detailed installation space

*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:

1. The total short-circuit current of PV string must not exceed inverter’s max DC current.
2. The minimum isolation resistance to ground of the PV string must exceed 19.33kQ in case of any shock hazard.
3. PV string could not connect to earth/grounding conductor.
4. Use the right PV plugs in the accessory box.

Step 1. Prepare PV positive and negative power cablesStep 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.

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

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.

1. 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

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 

Table 4.4-1 :Smart Meter LED Indications

Connection Mode
The connection diagram on the instrument housing shall prevail in case ofany discrepancies with it. Itis recommended to use 0.5A or 3A for the fuse in the connection diagram;
Make sure the inverter is totally isolated from any DC or AC power before connecting AC cable. Table 4.4-2 :RS485 interface

The Smart Meter with CT in product box is compulsory for IVGM system installation, used to detect grid voltage and current direction and magnitude, further to instruct the operation condition of IVGM inverter via RS485 communication. See Table 4.4-3.
Table 4.4-3 :Detailed Pin Function Of COM Port On IVGM

Make sure Meter & CT are connected between house loads and grid, and follow the Smart Meter direction sign on CT, refer to Figure 4.4-3.

4.5 Dry Contact Signal
There is one dry contact (34/250VAC) available on the inverter.

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

Step 3-2 For Remote Shutdown. Run the cable through the steel plate , Then wire from pins 5 and 6. Table 4.6-1 describes the 6-pin port definition, Wiring is shown in Figure 4.6-4.Step 4. Connect RJ45 terminal to the right position onto the inverter. See Figure 4.6-5. 4.7 Lithium Battery Communication
It’s allowed to connect lithium battery and build communication only which it has been configured. Please follow bellow steps to configure communication between lithium battery and inverter.

1. Connect power cables between lithium battery and inverter. Please pay attention to the terminals of positive and negative. Make sure the positive terminal of battery is connected to the positive terminal of inverter, and the negative terminal of battery is connected to the negative terminal of inverter.
2. The communication cable is bundled with lithium battery. Both sides are RJ45 port. One port is connected to the BMS port of inverter and another one is connected to the COMM port of lithium battery.
