Set BLUETTI EP2000 inverter + 2 batteries B700

Bluetti EP2000 & B700 solar storage battery

The Bluetti EP2000 & B700 is a high-performance, complete solution for retrofitting existing solar power systems, especially for systems that will no longer be eligible for feed-in tariffs 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 output: 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%
• Switchover time to emergency power: <10 ms
• Protection class: IP65 (dustproof and splashproof)
• Battery chemistry: safe LiFePO₄ technology
• Warranty: 10 years

Advantages of retrofitting old PV systems

• Compatible with existing inverters (AC coupling possible) – the system can continue to operate without major modifications. Replacing the existing inverter is not necessary. The wiring of the PV modules and inverter also remains unchanged.
• Higher self-consumption rate : Instead of feeding the solar power into the grid, it is stored directly and used in the house.
• Reducing electricity costs : Particularly interesting after the end of the feed-in tariff, when grid electricity has to be purchased at a high price.
• Backup function : Thanks to switching in under 10 ms, the power supply is ensured even in the event of a power outage.
• Flexible expansion : With up to 7 B700 batteries or several EP2000 units connected in parallel, even larger houses, businesses or agricultural properties can be supplied.

Typical areas of application

• 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, cooling systems or e-charging stations.
• Commercial retrofitting : Combination of self-consumption optimization and emergency power supply.

Security

The EP2000 & B700 utilize LiFePO₄ battery cells , which offer exceptionally high thermal stability and longevity compared to other technologies. The integrated BMS (Battery Management System) protects against overcharging, deep discharging, and short circuits. Additionally, the IP65 protection rating and automatic switchover in the event of a power failure ensure safe operation even under adverse conditions.

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

Stringent safety certification: Battery – IEC62619, IEC60529, UN38.3, VDE2510-50, ISO13849, 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 conventional low-voltage (LV) batteries, the Bluetti EP2000 & B700 use 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.
