Hoymiles Base LB-(5-20)S-G2-Base for LB-5S-G2

Mounting Base LB-(5-20)S-G2-Base (for LB-5S-G2 systems)

The base is designed as a mechanical element of the Hoymiles LB-(5-20)S-G2 battery set. It allows stable mounting of battery modules in tower configuration (1–4 PACK modules) and provides a grounding connection and mounting point for the controller.

Manufacturer: Hoymiles Power Electronics Inc. — manufacturer of energy storage systems with technical documentation describing mounting components (base, brackets) for the LB-(5-20)S-G2 series.

Electrical and Functional Parameters

• Grounding connection: grounding terminal at the back of the base; supplied grounding wire with a specification of 6 AWG / 16 mm².
• Current purpose of the system: maximum allowable charging/discharging in accordance with battery modules — up to 200 A per tower.
• Cable compatibility: recommended cross-sections of power cables depending on inverter power and configuration (e.g., 4 AWG/25 mm² for inverters ≤6 kW; 2/0 AWG/70 mm² for higher powers or parallel connections).
• Mounting elements included: bracket C (left/right), bracket B, screws M4, M5, M6, and expansion plugs according to the packaging list.
• Installation recommendations: mounting on a horizontal, stable surface; use a detector before drilling to detect wires and pipes.
