Is EGbatt a Lithium Battery manufacturer?

Yes. EGbatt is a manufacturer located in Shenzhen, Guangdong, China. It designs and produces LiFePO4 battery packs for energy storage, electric forklifts, marine applications, golf carts, RVs, and UPS systems.

What is the production lead time?

Based on automated production technology, the current product lead time is 15-25 days.

Which battery cells does EGbatt use?

The company has strategic cooperation agreements with top manufacturers like EVE and REPT, and insists on using A+ tier One lithium iron phosphate cells for its solar batteries.

Which inverters are compatible with EGbatt batteries?

For 48V inverters, compatible brands include Victron Energy, Goodwe, Studer, Solis, LuxPower, and others. For high-voltage three-phase inverters, compatible brands include Atess, Solinteg, SAJ, Goodwe, and Solis.

What is the warranty for EGbatt energy storage batteries?

EGbatt offers dealer customers a 10-year warranty and technical service for its energy storage battery products.

What is Depth of Discharge (DoD)?

DoD describes how much of the battery's capacity has been used. A DoD of 100% means the battery is completely empty, while 0% means it is full.

What is State of Charge (SoC)?

SoC reflects the battery's charge level. A SoC of 100% means the battery is full, and 0% means it is empty.

What is C-rate?

C-rate, or power factor, indicates how quickly a battery can be charged or discharged relative to its capacity. A rating of 1C means the battery can be fully charged or discharged in one hour.

What is the cycle life of a EGbatt Lithium Solar Battery?

The battery uses Lithium Iron Phosphate chemistry and provides a cycle life of over 6,000 cycles at 90% Depth of Discharge, and over 10 years at one cycle per day.

What is the difference between kW and kWh?

kW (kilowatt) is a unit of power, measuring the rate of energy production or consumption. kWh (kilowatt-hour) is a unit of energy, measuring the total amount of work done or energy used over time.

Where can a home battery be installed?

EGbatt home batteries are suitable for both indoor and outdoor installation (depending on the model's protection level) and offer floor-standing or wall-mounted options. Common locations include garages, attics, or under eaves.

How long can a 10kWh Powerwall run home appliances during a power outage?

This depends on the load. As a realistic example, a 10kWh battery could run ten 100-watt light bulbs for 12 hours without recharging.

How many home batteries does my house need?

The number varies based on home size, energy consumption history, and personal goals (like which devices to run during an outage). For most systems, 2 or 3 batteries are installed. A detailed discussion of your needs is recommended for an accurate assessment.

Can I go completely off-grid with solar and batteries?

Yes, it is possible, but it requires careful planning and significant investment. A true off-grid system needs a large enough solar array and sufficient battery storage to sustain your lifestyle. Cost and having an alternative energy source for when solar charging isn't possible are key considerations.

Is EGbatt an online store?

No. EGbatt focuses on building long-term relationships with business partners like battery distributors, solar equipment dealers, and installation contractors worldwide, not direct sales to end consumers.
