Details of the ZYC SIMPO HV 6.4 kWh Battery Pack
ZYC SIMPO HV 6.4 kWh Battery Pack: complete tower, ready for installation
The ZYC SIMPO HV is the battery of high voltage from ZYC Energy: a modular tower with direct current coupling which works directly with the hybrid inverter, without double conversion, to store solar energy with minimal losses.
This pack includes 2 modules of 3.2 kWh on the BMS unit and base, making a total of 6.4 kWh a 128 V nominal. The whole set is stacked screwless, with quick-connect plug-in terminals, and takes up 610 × 240 mm floor area — 30 % less than a conventional cupboard with the same power rating.

Why this battery?
- Load at -10 °C. It maintains the charge below zero, whereas most high-voltage LFP batteries cut out at 0 °C.
- IP65. It can be installed indoors or outdoors, without the need for an additional cabinet.
- It grows with you. Modules are added to the tower or towers in parallel, whilst the system is running, without altering the architecture.
- Quick installation. No screws, no wiring between modules: it simply stacks and clicks into place.
Compatibility
It requires a high-voltage hybrid inverter Compatible via CAN or Modbus RS485. It is not compatible with 48 V systems (Victron, Deye 48V…); for such installations, the ZYC option is the SIMPO 5000. Please check with us to ensure compatibility with your inverter before ordering.
Compatible inverters
Compatibility verified by ZYC on its official list SIMPO HV Inverters Compatibility List V1.7 (June 2025) with Kostal (PLENTICORE G3, PLENTICORE plus G2, PLENTICORE BI G2 and PLENTICORE MP S G3), Solis (S6-EH3P and RHI-3P HVES series), GoodWe (ET, EH, BH and EHB series), Solinteg (MHS and MHT) and Deye (SUN-SG01HP3, 5 to 50 kW).
Bear this capacity in mind: 6.4 kWh is the configuration supported by the fewest models. It is compatible with the Kostal PLENTICORE G3 and MP S G3, the entire Solis S6-EH3P series, the GoodWe EH, BH and EHB series, and the Solinteg MHS, but not with Deye neither with the GoodWe ET series nor with the PLENTICORE plus/BI G2.
A minimum firmware version is required on the BMS, depending on the inverter brand: V1.5.0 for Kostal and Solis, V1.7.0 for Deye and V1.9.3 for Solinteg. To connect several towers in parallel, the ZYC combiner box is used: SCB3-50A up to 3 towers and SCB8-50A up to 8.
