Product Name: Household PV On-Off-Grid Energy Storage System
Product Model: ES2.9KWHPV1
Household PV on-off grid energy storage system made by Guangzhou Great Power Energy & Technology Co. Ltd., our parent company listed on Shenzhen’s GEM, Stock Code: 300438, adopts lithium iron phosphate battery with more than 10 years’ lifespan and intelligent BMS system, and can be widely used in the followings.
- Rural families
- Families of villages and towns
- Border outpost and barracks
- Areas of inadequate electricity supply
- Remote mountainous areas
- Remote schools
- Active equalization: By adopting the centralized two-way nondestructive active balance transfer technology, the maximum equalization current can be up to 5A. The discharge energy of high monomer battery is transferred to a low monomer battery which will increase 25% of battery life.
- Low-power management: By adopting our self-developed low power management technology, the stand-by power consumption of battery is reduced to 0.5W per hour which has solved the power consumption of BMS and improved energy utilization and the product transportation and storage of the battery.
- Floating management technique: By adopting the BMS intelligent charging floating management technique, it can avoid a long period of high voltage battery state of constant voltage which will increase the reliability and cycle life of the battery.
- Battery module thermal management technique: By adopting battery module thermal management technique, it can ensure the battery working temperature uniformity and avoid the inconsistency of capacity and voltage of the cells caused by the temperature difference which will prolong the service life of the battery pack.
- Multidimensional SOC estimation technique: By adopting multidimensional SOC estimation technique, it can avoid over current, over voltage, over temperature, overload, short-circuit protection, over charge and over discharge of battery and balance the battery which will improve the safety and service life of battery.
- Two kinds of AC output voltages: By outputting two kinds of AC voltages of 110V and 220V, it can be used in various countries and regions.
