Chinese inverter manufacturer GoodWe has launched a new hybrid inverter line for residential PV systems.
“The product features a data display showing power generation data,” a spokesperson told pv magazine. “This ensures PV system owners can monitor their installations even in locations with weak or no wireless signal.”
The ES Uniq Series is available in two variants – with 3 kW to 6 kW and 8 kW to 12 kW of capacity.
The smaller line is offered in four versions with a power output of 3 kW to 6 kW, a maximum PV input power of 6 kW to 12 kW, and a maximum input voltage of 600 V. It features one maximum power point tracking (MPPT) for string and two MPPT trackers per string
The largest series includes three models with power outputs from 8 kW to 12 kW, a maximum PV input power of 16 kW to 20 kW, and a maximum input voltage of 600 V. It features two maximum power point trackers (MPPT) for strings and two trackers per string.
Both products feature an MPPT operating voltage ranging between 60 V and 550 V and a nominal input voltage of 360 V. The maximum efficiency is 97.6% and the European efficiency rate is 96.2%. The maximum output current is between 15 A and 30 A for the smaller line and 50 A for the largest.
The inverters have IP66-rated protection and operate within a temperature range of -35 C to 60 C. They come with integrated surge protection for both DC and AC.
“The inverters offer versatile compatibility with both on-grid and off-grid applications, featuring UPS-level switching to backup mode in under 10 milliseconds,” the spokesperson said. “It supports parallel connections of up to 16 inverters, enabling seamless system expansion. The largest product is designed to work seamlessly with 182mm modules, providing a 200% oversizing capacity.”

The report does not state whether the inverters are for low voltage batteries or high voltage batteries.
Also, with the
““This ensures PV system owners can monitor their installations even in locations with weak or no wireless signal.”
the report does not state how this is done – if it does not rely on the SEMS portal for users to monitor the performance, does it then, provide connection to a LAN at the user’s property, for example, like a network printer, accessed through a wifi router at the property, so that the user logs directly into the inverter, through a wifi router, for the data to monitor the inverter, or, does it use an application to be installed on the user’s computer, and, if so, is it then operating system dependent, and, if so, with which operating systems, is it compatible?
Hi Bret, thank you for taking an interest. The information in the article was supplied by a GoodWe spokesperson at the trade show and as you have discovered, more detailed information is available via the company’s datasheets.
At
https://en.goodwe.com/es-uniq
only the
“8-12kW │Single Phase│2 MPPTs│Hybrid Inverter (LV)” range is shown, and it is shown as working with low voltage batteries.
This “new” inverter range seems to be simply an extension (8kW, 10kW, and 12kW) of higher capacity versions of the range at
https://en.goodwe.com/es-series-single-phase-hybrid-solar-inverter
(“3.6-5kW | Single Phase | 2 MPPTs | Hybrid inverter (LV)”).
The datasheet at
https://www.goodwe.com.au/Ftp/EN/Downloads/Datasheet/GW_ES-Uniq_Datasheet-EN.pdf
refers to communications for monitoring, being only with the SEMS portal.
The only apparent innovation (other than the additional inverter capacities), appears to be that the inverter range will take input from generators, in addition to input from a stationary battery system; some people have claimed that where a PV inverter has an input port for generators, that port can be used for taking input into the system, from a BEV’s V2L output.
