Sunsynk 80kW Three-Phase High-Voltage Hybrid Inverter

Sunsynk 80kW Three-Phase High-Voltage Hybrid Inverter

The Sunsynk SUNSYNK-80K-SG02HP3-EU-EM6 is a commercial-grade three-phase hybrid inverter designed to coordinate solar generation, high-voltage lithium-ion battery storage, grid supply and backed-up loads through one intelligent energy platform. With 80kW rated active power, two independent battery inputs and extensive PV capacity, it is suited to businesses, farms, warehouses, offices, retail facilities and other sites that require robust energy management and greater protection against grid interruptions.

High-capacity commercial energy management

The inverter delivers 80,000W rated AC input/output active power and supports up to 88,000VA apparent power. A maximum continuous AC passthrough rating of 200A allows substantial grid power to feed connected loads when required. In off-grid operation, the unit can supply a short-duration peak of 1.5 times its rated power for 10 seconds, helping it accommodate demanding motor-starting and transient loads when the system has been correctly designed.

Extensive solar input with six MPPT trackers

Six MPPT trackers, each supporting two PV strings, provide twelve string connections and allow a system designer to divide the array across different roof sections, orientations or operating conditions. The inverter accepts up to 128kW maximum PV input power and 160kW maximum PV access power. Its 150-850V MPPT operating range and 1,000V maximum PV input voltage support efficient high-voltage string design for larger commercial arrays.

With a maximum efficiency of 98.7%, Euro efficiency of 98.1% and MPPT efficiency greater than 99%, the inverter is engineered to convert available solar energy efficiently across changing operating conditions. The full-load MPPT range of 485-850V provides a clear design window for achieving full rated output, subject to professional string calculations and local electrical requirements.

Dual high-voltage battery inputs

Two battery inputs support compatible lithium-ion batteries operating from 160V to 1,000V DC. Each input is rated for up to 80A charging and 80A discharging, giving the inverter a combined specified current arrangement of 80A + 80A. Battery charging adapts to the connected battery-management system, allowing the inverter and compatible battery BMS to coordinate charge and discharge limits.

This high-voltage architecture is intended for suitably matched commercial battery systems. Standard 48V low-voltage batteries are not compatible. Battery selection, usable capacity, maximum current, communications and firmware compatibility must be confirmed before installation.

Three-phase grid and backup capability

The 3L+N+PE connection supports 220/380V and 230/400V three-phase networks. The inverter operates on 50Hz or 60Hz systems within the datasheet limits and provides adjustable power factor from 0.8 leading to 0.8 lagging. Total current harmonic distortion is specified below 3% at nominal power, supporting high-quality power conversion when the system is correctly commissioned.

Hybrid operation enables solar energy to serve site loads, charge compatible battery storage and work alongside the utility supply according to the final system design. For backup applications, essential and non-essential loads must be separated and engineered around the inverter, battery and switchgear ratings. Runtime depends on the connected battery capacity, battery state of charge and actual site consumption.

Protection for demanding installations

The inverter incorporates DC polarity-reversal protection, AC overcurrent and overvoltage protection, short-circuit and thermal protection, insulation-impedance monitoring, DC-component monitoring, ground-fault and earth-fault detection, anti-islanding monitoring, residual-current detection, an integrated DC input switch and surge protection. Type III surge protection is specified on both the DC and AC sides, while optional arc-fault circuit interruption is available according to the supplied configuration.

An IP65 enclosure provides protection for suitable indoor or outdoor installation locations, while intelligent cooling manages heat under load. The operating temperature range is -40°C to +60°C with derating above 45°C, and the permissible installation altitude is up to 3,000m. The 105kg inverter must be transported and installed by qualified personnel on a structure with adequate load-bearing capacity.

Monitoring and system integration

An LCD and LED interface provides local system information. RS232, RS485 and CAN communications support equipment and battery integration, while optional GPRS, Wi-Fi, Bluetooth, 4G and LAN monitoring options allow performance and operating data to be accessed according to the installed communications hardware and platform configuration.

Compliance and warranty

The datasheet lists NRS 097-2-1 grid-connection compliance, together with IEC/EN 61000-6-1/2/3/4 and IEC/EN 62109-1/-2 EMC and safety standards. The standard warranty is five years. The datasheet specifies a ten-year warranty when the inverter is installed with a Sunsynk battery; registration, commissioning, approved equipment and all manufacturer warranty conditions still apply.

Professional system design required

This inverter forms part of a professionally engineered commercial energy system. Final battery-bank voltage, PV string design, switchgear, protection, cable sizing, backup-load allocation, grid approval and commissioning must be completed by suitably qualified professionals. Batteries, solar panels, mounting equipment, switchgear, cables, monitoring accessories, transport and installation are not included unless specifically stated in the quotation.

Frequently asked questions

Can this inverter use a standard 48V battery?

No. It requires a compatible high-voltage lithium-ion battery system operating within the specified 160-1,000V DC battery range.

How much solar PV can be connected?

The datasheet specifies 128kW maximum PV input power and 160kW maximum PV access power. The final array must also comply with the voltage, current, MPPT and string limits.

How many MPPT trackers does it have?

It has six MPPT trackers with two strings per MPPT, providing twelve PV string connections.

Is it suitable for outdoor installation?

The inverter has an IP65 ingress-protection rating. The installation location must still comply with the manufacturer manual, environmental limits and structural requirements.

What warranty is included?

The datasheet states a five-year warranty, extended to ten years when installed with a Sunsynk battery, subject to the manufacturer’s registration and warranty conditions.
