Description of 15kWh Battery

15kWh battery is a high-quality battery pack for home energy storage. It consists of three 5kWh batteries in parallel, using safe lithium iron phosphate battery cells. It ensures safety, reliability, and cost-effectiveness.

The 15kWh battery, as the most environmentally friendly home storage battery on the market, has a high-quality cell, flexible modular design and all-around safety performance that is widely used in large families, villas, hotels, travel agencies, small and medium-sized businesses, factories, hospitals and many other places that use a lot of electricity.

10kWh 51.2V 300Ah Lithium Battery Power Features

Large enough capacity: 15kWh battery capacity can meet the daily electricity demand of a 8-person family or an ordinary villa, as well as the electricity consumption of a small business, factory. It can largely help you to reduce your dependence on grid power and cut down on your energy bills.

A-grade EVE or REPT cell: The battery is made of A-grade EVE or REPT battery cell, which is the top three battery cell brands in China. The number of cycles can reach more than 6,000 and it can be used for 10~15 years under normal conditions. The speed during charging and discharging is only 0.5C, and the temperature change during charging is less than 10%. The decay rate of battery capacity is within 1.5%.

Rack design with battery case: The rack design of the battery structure makes it easier to assemble and the capacity of the battery is more flexible to choose. The metal case of the battery can separate the battery pack from the external environment and provide better safety protection, avoiding the occurrence of electric shock and reducing the possibility of damage to the battery.

Pre-set PV inverter protocols: All batteries are factory pre-set to communicate with major brands such as Growatt, Deye, Solis, Goodwe and many more. You can also tell us the brand name of your solar inverter and we will find and match it.

Ventilation design: 15kWh battery cabinet has ventilation design, which mainly serves as heat dissipation. It further ensures the constant temperature when the battery is working.

Clear cable connection: the connection cable between the battery modules is simple and easy to understand, you can refer to the following diagram for the connection of the connection assembly circuit.

Low voltage design: The 48V battery system is safer than the high voltage system, and it can also meet the battery voltage requirements of most of the solar inverters under 20KW.

Safety: The battery has passed a number of tests such as explosion-proof, drop test, anti-puncture test, over-temperature, over-voltage, over-current and so on. Let you no longer have any worries in the process of using.

High efficiency: The energy efficiency of traditional lead-acid batteries is about 50%~70%, and the efficiency of charging and discharging in the last 20% will be very low. But the energy efficiency of lithium iron phosphate battery can reach more than 95%. The charging and discharging time is shorter, and the energy loss is less.

Maintenance-free design: We all know that if lead-acid batteries are left for a long time, the sulfuric acid in the electrolyte will be gradually salinized when the power is insufficient, making the capacity and efficiency of the batteries will be low. And you have to add distilled water regularly. But lithium iron phosphate batteries do not worry about this situation, the use of the process or long-term placement basically does not require any maintenance.
