FAQ

HiOne works with a compatible solar PV system to coordinate solar generation, battery charging and household electricity consumption. Excess solar energy can be stored in the battery and used later when solar generation is lower, such as in the evening. Actual performance depends on system configuration, weather conditions and household energy use.

HiOne is designed for residential solar and storage applications. Whether it can be integrated with your existing rooftop solar system depends on your current inverter, PV system configuration and the selected HiOne model. Consult a qualified installer to confirm compatibility before installation.

HiOne can help households store surplus solar energy that might otherwise be exported to the grid. This can be useful for homes with substantial daytime solar generation and evening electricity consumption. The right battery capacity depends on your solar output, daily energy usage and preferred level of backup.

Yes. HiOne features a plug-and-play design and wire-free battery stacking to simplify installation. The standard installation process can take as little as 15 minutes for battery stacking, cable connections and cloud commissioning under suitable conditions. Actual installation time depends on site conditions, electrical work and system configuration. Electrical installation must be performed by appropriately qualified professionals.

HiOne can help households increase solar self-consumption by storing excess daytime solar generation for use when electricity demand is higher or solar production is lower. Depending on your electricity plan, it may also help you manage time-of-use tariffs. Actual savings depend on your tariff, feed-in rate, energy usage, system size and operating settings.

HiOne can support home backup applications when installed with the required compatible backup equipment and configured appropriately. The circuits and appliances supported during an outage depend on the system design, available battery energy, inverter output and local product specifications. Ask your installer to confirm which essential loads can be backed up.

HiOne supports cloud-based intelligent commissioning through the S-Miles Cloud/App, reducing the need for complex manual setup. Its automatic self-inspection function can detect approximately 90% of common installation faults during commissioning, including reversed CT connections, loose cables and abnormal grid-connected parameters, and provide real-time alerts.

The standard package includes accessories such as mounting brackets, expansion screws, positioning plates and communication cables. Typical tools include a tape measure, level, electric drill, torque wrench, wire stripper and multimeter. Qualified installers should follow the official installation manual and applicable Australian requirements.

HiOne integrates multiple electrical safety protections, including arc-fault circuit interruption (AFCI), anti-islanding protection, PV reverse-polarity protection, residual current monitoring, AC overvoltage and undervoltage protection, short-circuit protection, and Type II DC and AC surge protection. These built-in features help support safe system operation. The final installation must also comply with applicable Australian electrical and grid connection requirements.

The recommended maximum PV input power depends on the inverter model. The 12 kW single-phase model supports up to 24 kW of recommended PV input power, while the 20 kW three-phase model supports up to 40 kW. The series supports up to four MPPTs, with input current ratings of up to 18 A per channel for single-phase models and 20 A per channel for three-phase models. Maximum PV voltage is 600 V for single-phase models and 1,000 V for three-phase models. Installers must verify all electrical limits against the specific model datasheet.
