EG4 Electronics is a provider of components for solar energy systems and battery-based energy storage. The company offers a number of different battery and energy storage systems (ESSs) for home and business owners. Its systems and components are known for integrating well with components from other manufacturers as well.
The company offers off-the-shelf parts, like rackable batteries and cabinets. It also offers complete energy storage systems that include inverters and automatic shut offs that allow the system to island from the electric grid in a blackout situation.
The company’s offerings include the WallMount, LifePower4 and LL (Lifetime Lithium) battery lines. Their ESS solutions are called PowerPro and include indoor and outdoor mounted systems.
The EG4 WallMount batteries are offered as either an indoor or All Weather outdoor battery. It’s a 48V 280Ah Lithium Iron Phosphate (LiFePO4) battery or 14.3 kilowatt hour (kWh) backup battery. It’s designed for DC configurations.

The EG4 LL and LifePower 4 are rackable LiFePO4 batteries, requiring connection and storage on a rack or in a cabinet. Additionally, they’re modular, and EG4 states that some models can be connected in systems to store 80 kWhs or more depending on the unit type and system.
EG4 calls its line of ESS solutions the PowerPro line. Moreover, homeowners and business owners can install an ESS that charges from the electric grid and takes advantage of time of use pricing schemes to help them save on electric costs, while the ESS systems work with solar systems.
The ESS systems are modular, designed for flexibility, and are configurable in many different ways. For instance, a homeowner can get a PowerPro system with one or two All Weather WallMount batteries to mount outside their home. Conversely, a small business, on the other hand, may opt for a PowerPro system with cabinets that can hold up to 12, 5.12 kWh rackable batteries for a 61.44 kWh system.
With a shut-off switch, the ESS systems can provide backup power and island from the electric grid in a blackout situation. Furthermore, the systems are also configurable to provide electricity to the grid when prices are high and to pull electricity from the grid when prices are low.

Depending on the product, EG4 offers 5 to 10 year warranties. Additionally, the majority of its products come with a 10-year warranty and the LifePower4 batteries have a 5 year warranty that’s extendable to 10 years when paired with an EG4 inverter.
An EG4 battery can last for over 15 years.
The EG4-LL batteries have a round-trip efficiency of 94.5%, which means that for every 14.3kWh of electricity you put into the battery, you can get back up to 13.51kWh due to its complex chemical characteristics and efficient BMS.
Some manufacturers are known for employing higher-quality materials and manufacturing batteries with longer lifespans and greater efficiency. EG4 batteries are some of the bests on the market, and they come in a variety of capacities and features.
It’s essential that you consider your roof’s dimensions, shape, and slope. Although other roofs might work, south-facing roofs with a slope of 15 to 40 degrees are usually the ideal for solar panels. The age of your roof and when it will need to be replaced should also be taken into account.
An EG4 battery should only be installed, operated, and maintained by a certified solar installer, such as Solar SME. Additionally, confirm that the battery and rack are grounded correctly.
