400V HV Battery for SolArk, Deye, GoodWe & Other High Voltage Hybrid Inverters

The EGbatt Hbrick-HV50A is a 400V DC high voltage battery engineered specifically for modern high voltage hybrid inverters that require a 330–450V DC input. Unlike 48V batteries that need external transformers, this native HV battery communicates directly via CAN bus or RS485, delivering plug‑and‑play compatibility with leading inverter brands.

Which Inverters Are Compatible with the Hbrick-HV50A?

The Hbrick-HV50A has been tested and verified to work with the following high voltage hybrid inverters. If your inverter accepts 330–450V DC and supports CAN or Modbus communication, it will likely work – but the models below are confirmed.

Sol-Ark (All HV Series)

Sol-Ark’s high voltage inverters (e.g., 12K, 15K, 30K) operate with a 300–450V DC battery input. The Hbrick-HV50A matches perfectly. Use CAN1 port on the inverter, select “Lithium Battery” mode, and choose “EGbatt” protocol (or “User‑defined” with voltage limits 330–450V).

Deye (SUN-*K-SG04LP3-EU Series)

Deye’s popular SUN-5/6/8/10/12K-SG04LP3-EU inverters are designed for 160–700V DC batteries. The Hbrick-HV50A’s 330–450V output sits in the sweet spot. Connect to the BMS port (CAN), set “Lithium” mode, and select CAN protocol ID 00 (or auto‑detect).

GoodWe (EH, BH, HT Series)

GoodWe’s high voltage batteries (e.g., EH-5.0/6.6/8.0/10.0, BH, HT) accept 200–600V DC. The Hbrick-HV50A is compatible via RS485 or CAN. Set inverter to “Lithium” and choose “GoodWe” or “Custom” protocol with voltage range 330–450V.

Growatt (MIN, MOD, SPA Series)

Growatt’s HV hybrid inverters (MIN 2500-6000TL-XH, MOD 3000-6000TL3-XH, SPA series) accept 150–600V DC. The Hbrick-HV50A works via CAN. Select “Lithium Battery” and “CAN” communication. If EGbatt is not listed, use “User‑defined” voltage.

Sungrow (SH Series)

Sungrow SH inverters (e.g., SH5K, SH8K, SH10K) are natively high voltage. Connect via RS485. Set battery type to “Lithium”, then choose “General” or “Custom” with min voltage 330V, max 450V.

Sofar, LuxPower, Victron (with HV Interface)

Sofar HYD series, LuxPower ACS series, and Victron MultiPlus-II with HV battery interface are also compatible. Use CAN or RS485 as per inverter manual. Contact EGbatt support for protocol files if needed.

Plug-and-Play Communication: CAN Bus & RS485 Pinouts

The Hbrick-HV50A provides two standard communication ports:

• PCS port (RJ45) – CAN 2.0B for inverter communication
• PC/PAR port (RJ45) – RS485 (Modbus) for monitoring or PC connection

CAN Bus Pinout (PCS Port)

Note: Most HV inverters (Deye, SolArk, GoodWe) use pins 4/5 or 5/6 for CAN. If your inverter follows a different pinout, a simple adapter cable can be made – contact EGbatt for a custom wiring diagram.

RS485 Pinout (PC/PAR Port)

For Modbus monitoring, connect to pins 1 (A) and 2 (B). The default baud rate is 9600 (configurable via PC software).

Why High Voltage (400V) Batteries Are Required for Modern Hybrid Inverters

Modern hybrid inverters from SolArk, Deye, GoodWe, and others are designed with high voltage DC inputs for several reasons:

• Efficiency: Operating at 400V reduces current by a factor of ~8 compared to 48V, cutting resistive losses (I²R) dramatically.
• Simplicity: No external transformer or heavy copper busbars needed.
• Scalability: HV inverters can easily handle 10–100kW by adding battery modules in series/parallel.
• Safety: Lower current reduces heat and fire risk.

If you connect a 48V battery to an HV inverter, you will need an expensive step‑up transformer (which adds losses, cost, and failure points). The EGbatt Hbrick-HV50A eliminates that need entirely.

Technical Data for Inverter Integration

When programming your inverter, use the following parameters:

Inverter Settings – Quick Reference

Sol-Ark

Menu → Battery → Type: Lithium → CAN → Baud rate 500k → Protocol: EGbatt (or “Custom”). Set voltage limits 330V min, 450V max.

Deye

Battery → Type: Lithium → Communication: CAN → Protocol ID: 00 (auto). If not recognized, choose “User” and set float/bulk/absorption voltages according to Hbrick-HV50A spec sheet.

GoodWe

In SolarGo app or LCD → Battery → Type: Lithium → Brand: General → Protocol: RS485/CAN. Set voltages: Absorb 450V, Float 400V, Shutdown 330V.

Growatt

LCD → Battery Type: Lithium → Communication: CAN → Battery brand: Other → Voltage range 330–450V. Set max charge/discharge current based on your parallel count (e.g., 16A × number of units).

Troubleshooting Communication Issues

If your inverter does not recognize the battery:

1. Check cable orientation (straight-through vs crossover; EGbatt uses straight-through).
2. Verify inverter’s CAN/RS485 port is active (some inverters require a termination resistor – EGbatt can provide).
3. Update inverter firmware to latest version.
4. Contact EGbatt support with inverter model and BMS log file (available via PC software on PAR port).
