Set BLUETTI EP2000 inverter + 2 batteries B700

Bluetti EP2000 & B700 Solar Storage Battery

The Bluetti EP2000 & B700 is a powerful complete solution for retrofitting existing solar systems, especially for systems that are no longer eligible for EEG funding after 20 years. Many operators want to continue using their existing PV modules – here, the combination of the EP2000 hybrid inverter and the modular B700 LiFePO₄ storage batteries offers a future-proof solution.

Technical Specifications

• Hybrid Inverter Power: 10.5 kW to 20 kW (with 2–7 B700 batteries)
• Storage Capacity: 14.7 kWh to 51.6 kWh (expandable)
• PV Input: up to 30 kW, 1000 V maximum voltage
• Efficiency: up to 97.6%
• Backup Power Switching Time: <10 ms
• Protection Class: IP65 (dust and splash-proof)
• Battery Chemistry: safe LiFePO₄ technology
• Warranty: 10 years

Advantages for Retrofitting Old PV Systems

• Compatible with existing inverters (AC-coupling possible) – the system can continue to operate without major modifications. No replacement of the existing inverter is necessary. The wiring of PV modules and inverter also does not need to be changed.
• Higher self-consumption rate: Instead of feeding solar power into the grid, it is stored directly and used in the house.
• Reduce electricity costs: Particularly attractive after the end of feed-in tariffs, when grid electricity has to be purchased at a high price.
• Backup function: Thanks to switching in less than 10 ms, the supply is secured even in the event of a power outage.
• Flexibly expandable: With up to 7 B700 batteries or several EP2000 units connected in parallel, larger houses, businesses, or agricultural properties can also be supplied.

Typical Applications

• Private households with older PV systems: ideal for continuing to use existing solar modules economically.
• Small businesses and workshops: reliable power supply even during peak loads.
• Agriculture and farms: supply of heat pumps, refrigeration systems, or EV charging stations.
• Commercial retrofitting: combination of self-consumption optimization and emergency power supply.

Safety

The EP2000 & B700 uses LiFePO₄ battery cells, which offer particularly high thermal stability and longevity compared to other technologies. The integrated BMS (Battery Management System) protects against overcharging, deep discharge, and short circuits. In addition, the protection class IP65 and automatic switching in the event of a power outage ensure safe operation even under adverse conditions. 

The solar storage system has 6 levels of safety to protect your beloved home: Battery level, PACK level, PCS level, structural level, emergency protection (pressure relief valve, etc.), network security, and data protection.

Strict safety certification: Battery – IEC62619, IEC60529, UN38.3, VDE2510-50, IS013849, EN/IEC 61000-6-1, EN/IEC61000-6-3, Inverter – IEC 62109-1, IEC62109-2, EN62109-1, EN62109-2

High-Voltage System and its Advantages:

Unlike classic low-voltage (LV) storage systems, the Bluetti EP2000 & B700 operates with high-voltage (HV) technology. Advantages:

• Higher efficiency due to lower line losses
• More compact design with the same performance
• More power per module: up to 20 kW output power and 30 kW PV input
  This makes the system particularly suitable for high-performance households, small businesses, and users with high energy demands, while LV systems are more commonly used in small residential areas.
