Growatt HVC 60050-C2 – BMS for ARK HV (incl. SPH cable set)

The Growatt HVC 60050-C2 is the battery management system unit (BMS/BCU) for the
Growatt ARK high-voltage battery system. This version is supplied with a cable set for SPH inverters
(communication & power supply), so you no longer need to order a separate set. Place the BMS on top of the ARK stack;
It monitors the cells, balances, communicates with the inverter and ensures safe charge/discharge control.

Application & compatibility

• Inverter: Growatt SPH series (hybrid, 3-phase). Cable set for SPH is included in the scope of delivery.
• Batteries: Growatt ARK HV (e.g. ARK-2.5H-A1 modules). Minimum number of modules per stack according to ARK specification.
• Measurement: Use a Growatt 3-phase smart meter for export limitation and intelligent control.

Technical functions (short)

• BMS/BCU for HV stack: cell equalisation, SOC/SOH calculation, temperature/current protection.
• Communication to the inverter (including CAN/RS-485, depending on model), status LEDs.
• Installation position: on top of the ARK stack; fixed data and DC connections with upper battery module.
• Firmware: updateable via inverter/monitoring; logical menus for commissioning.

Installation instructions

1. Installation – first place the required minimum number of ARK-HV modules, snap on the BMS as the top unit and fasten according to the instructions.
2. Coupling SPH – use the supplied cable set (communication + power supply). Lay shielding neatly and maintain distance from AC power cables.
3. Smart Meter – mount the electricity meter directly behind the main connection for correct import/export measurement and battery logic.
4. Commissioning – via the inverter menu: Select battery type ARK HV, initialise SOC, set charge/discharge rules and test export limit.
5. Thermal & local conditions – Place the stack in a flat, ventilated location; avoid direct sunlight and temperatures below freezing during installation.
