The HGNESS HG-C&I-HV Series is a modular high-voltage lithium iron phosphate (LiFePO₄) battery system designed for commercial and industrial energy storage applications. Built around 5.12kWh stackable battery modules, the system offers configurations from 15.36kWh up to 61.44kWh, allowing storage capacity to be matched to different energy requirements.
With up to 100% depth of discharge, IP66 protection and integrated BMS protection, the system combines flexible capacity expansion with indoor or outdoor installation capability. Plug-in connections and a floor-mounted modular structure also simplify system installation and expansion.
The HG-C&I-HV Series is designed for applications including:
Pair the HGNESS HV Battery with the SOLIS S6-EH3P(10–29.9)K-H-AU hybrid inverter series for a complete solar and energy storage solution. The combination provides flexible battery expansion, intelligent energy management and reliable backup capability for commercial energy needs.
Bundle Special Offer: SOLIS inverter + HGNESS battery packages are available. (click here)
Each HG-C&I-HV system uses the HG-C&I-HVP 51.2V / 5.12kWh battery module. Systems can be configured with 3 to 12 modules, providing usable energy capacities from 15.36kWh to 61.44kWh.

The HG-C&I-HV Series uses LFP battery technology and incorporates all-round BMS protection and PACK-level fire protection. Its IP66-rated enclosure supports both indoor and outdoor installation, while the anti-dumping floor-mounted structure is designed to provide additional physical stability.
Operating temperatures range from 2°C to 55°C during charging and -20°C to 58°C during discharge. The system uses natural cooling, reducing reliance on active cooling components.
CAN and RS485 communication interfaces are supported, together with Wi-Fi connectivity. HGNESS also specifies online monitoring via apps, providing access to battery-system information for ongoing energy management.
The HG-C&I-HV Series lists the following certifications and standards:
UN38.3 / IEC 62619 / IEC 62040 / IEC 62477 / IEC 61000 / RoHS
Cycle Life: ≥6,000 cycles
Warranty: 10 years
The ≥6,000-cycle figure is based on test conditions of 25°C, 95% DoD, 0.2C charge/discharge and 70% end-of-life capacity. Warranty conditions are subject to the manufacturer's battery warranty terms.
The HG-C&I-HV combines high-voltage LFP technology with a highly scalable 5.12kWh modular architecture. Its 15.36–61.44kWh capacity range, up to 100% DoD, IP66 protection and indoor/outdoor installation capability make it a flexible storage platform for commercial and industrial solar and energy-management projects where future capacity expansion may be required.
All our products are covered by the Manufacturer's Warranty, which guarantees that they will be free from defects in materials and workmanship under normal use and service. The specific terms and duration of the warranty may vary depending on the product and the manufacturer. Please refer to the product's documentation or contact our customer support team for detailed warranty information.
Warranty Claim Process
In the unfortunate event that you encounter a faulty product, we want to make the warranty claim process as seamless as possible for you. To initiate a warranty claim, please follow these steps:
If damage is confirmed to be from normal wear-and-tear, drops, unauthorized repairs, or other non-warranty factors, service and shipping fees will apply. In such cases, we will contact the customer for approval before proceeding with paid repairs.
Unfortunately we cannot provide loaner units during the warranty repair process. For mission-critical equipment, we highly recommend purchasing backup units to prevent downtime in case of defects.
You have 30 calendar days to return an item from the date you received it.
To be eligible for a return:
Upon receiving your order, we kindly request that you thoroughly inspect all packages within 7 days of delivery. This inspection period is crucial as it allows you ample time to identify any visible damage caused during transit. Please keep in mind that promptly reporting any freight damage is vital in safeguarding your right to file a claim and ensuring a swift resolution.
Should you identify any freight damage during the inspection, we urge you to notify us immediately. Our customer support team is ready to assist you through the claim filing process and provide the necessary guidance to ensure a smooth and hassle-free experience.
The advertised price for this product includes the applicable STC battery rebate, applied as a pre-discount at the time of purchase.
To be eligible for the battery rebate:
Supply-only purchases are not eligible for the battery rebate.
By proceeding with this purchase, the customer agrees to assign all eligible Small-scale Technology Certificates (STCs) associated with the battery installation to Solar Battery Supermarket (or its nominated agent).
This assignment allows the rebate to be applied as a point-of-sale discount.
If the customer does not agree to assign the STCs, the full non-rebated price of the battery system will apply.
Installation by a licensed and accredited installer is mandatory to qualify for the rebate-adjusted price.
Standard metro installation is available from $500, subject to property assessment.
Additional works (including switchboard upgrades, long cable runs, or non-standard installations) may incur extra charges and will be quoted and approved prior to installation.
To assess eligibility and proceed with installation, the customer may be required to provide:
Failure to provide required information may delay installation or affect rebate eligibility.
This rebate offer does not limit your rights under Australian Consumer Law.
