Benefits of Growatt EG4 Batteries
Exceptional Durability:
Growatt EG4 batteries are made to last for over 7,000 deep charge and discharge cycles, so they will work reliably for years to come.
High Energy Density:
Growatt EG4 batteries have the highest energy density and are very small (3.5U). In this way, you can make better use of the space in your energy storage system.
Choices for Flexible Racking:
These batteries come with choices for flexible racks, which makes it easy to change how they are installed to fit your needs. Growatt EG4 batteries are good for the environment because they don’t contain any lead.
Reliable Built-In BMS:
Every Growatt EG4 battery has a reliable Battery Management System (BMS) that checks the voltage, current, temperature, and health of the battery as a whole.
Better safety features:
The Growatt EG4 batteries put safety first with E-Stop and two built-in fire suppressors, so you can use them without worry.
You can connect up to 64 Growatt EG4 batteries in parallel, which gives your energy storage system the most power and freedom.
What types of inverters are compatible with Growatt EG4 batteries?
Off-grid inverters from several manufacturers work with Growatt EG4 batteries. The built-in protocols of lithium-ion phosphate (LiFePO4) batteries enable simple integration and status monitoring with inverters. The inverter must recognize the EG4 battery’s communication protocol or have a lithium battery set to be compatible. Schneider, Magnum, and Outback off-grid inverters have been tested with EG4 batteries.
Use the included communication lines to connect EG4 batteries to an inverter. These connections link the battery management system (BMS) to the inverter also allowing it to monitor battery charge, voltage, and other vital information. After connecting the communication wires, the inverter may need to be tuned to recognize lithium batteries. Navigate to the battery settings menu and pick the lithium battery option. Compatible inverters allow EG4 battery owners to monitor battery consumption, establish low-voltage disconnect thresholds, and optimize their off-grid energy storage system.
Costs of Growatt EG4 Battery
Battery capacity, setup, and installation components affect Growatt EG4 battery prices.
- One Growatt EG4 lithium-ion battery, like the 48V 100Ah type, costs roughly $1,149. Its 5.12 kWh nominal capacity makes it suited for domestic energy storage and modest business settings.
- When developing a battery system consider how many batteries you need to satisfy your energy needs. A 30-kWh arrangement with six EG4 batteries would cost $6,894 without installation and equipment.
- The total cost may include installation. Depending on system complexity, hiring a skilled electrician to set up and integrate an inverter may cost several hundred to several thousand dollars.
- Despite the high initial cost, Growatt EG4 batteries generally pay for themselves in the long run by lowering energy bills and increasing energy independence.
Installation Process of Growatt EG4 Batteries
Putting in Growatt EG4 batteries is a simple process that only needs a few key steps. To help you with the process here is a full guide, such as
1. Gather Necessary Components
- Before you start, make sure you have everything you need, such as:
- EG4 batteries from Growatt
- Inverter that works with it (like Growatt, Schneider, Sol-Ark, or Victron)
- Cables for communication
- Hardware for mounting (if needed)
2. Set Up the Battery Configuration
Choose how you want your battery set up. You can put in a single battery or connect several cells in parallel to make the volume bigger. Put the batteries somewhere with good airflow, preferably close to the rectifier.
3. Connect Communication Cables
- To connect the batteries to your charger, use the connection cords that came with them.
- One end of the wire should be connected to the first battery’s transmission port.
- On the inverter, connect the other end to the port that goes with it.
- Using the extra transmission ports on each battery, daisy-chain them together if you are using more than one. This lets the inverter talk to all of the batteries in the system.
4. Set up the Inverter
After making the actual connections, set up your inverter so that it can see the Growatt EG4 batteries:
- On your inverter, go to the battery settings menu.
- Pick the right choice for the lithium battery.
For the exact steps, look at the guidebook that came with your inverter.
5. Monitor and Maintain
Your Growatt EG4 battery device will be ready to provide stable off-grid power after it has been set up and installed. Check the battery level often and do the maintenance the maker suggests to get the best performance and the longest life.

Performance of Growatt EG4 Batteries in Different Weather Conditions
Growatt EG4 batteries function well in most weather situations, however excessive temperatures might impair them. This is how they work in various environments:
Cold Weather Performance
Lithium-ion batteries like the Growatt EG4 lose efficiency and capacity in low conditions. Freezing may reduce lithium battery capacity by 20%. Growatt EG4 batteries include self-heating mechanisms that operate in low temperatures to sustain performance. User reports in off-grid installations have shown charging troubles in really cold situations. Low ambient temperature may prevent batteries from charging also resulting in low voltage problems if the solar panels are covered in snow and cannot produce electricity.
Hot Weather Performance
While lithium batteries perform well at high temperatures, continuous exposure to severe heat accelerates breakdown. Growatt EG4 batteries can tolerate extreme temperatures also assuring performance. Maintaining battery life requires enough airflow and avoiding direct sunlight.
Efficiency in general
With a round-trip efficiency of 99%, Growatt EG4 batteries can store and release energy efficiently. This efficiency is maintained in mild weather also making them a dependable home and business solution.
