Inverter Solis S6-EH3P30K-H, Three-phase, Hybrid, 30kW, High Voltage

This is a three-phase hybrid inverter of the commercial class: it links the solar panels, the batteries and the grid into a single system and constantly decides where the building is supplied from. Unlike domestic models, it has two battery ports managed separately, as if you had two independent tanks, which you can fill and empty according to different rules. When the grid is interrupted it takes over the supply so quickly that sensitive equipment, from computers to cash registers, does not even get to reset.

It supports up to 60 kW of panels, that is an installation of the order of 40-60 kWp, and delivers 30 kW to the loads, which covers an office building, a small hall or a housing complex. The backup output is also 30 kW and accepts peaks of 1,6 times the rated power for 2 seconds, enough for starting motors, and the switchover to backup mode is done in under 10 ms, practically instantaneously. Each of the two battery ports moves up to 33 kW at 70 A, so the system can charge a lot during sunny hours and can discharge quickly during the morning or evening consumption peaks. The four MPPT trackers with 8 string inputs allow roofs with several slopes and orientations, and the IP66 enclosure allows outdoor mounting; at 530 x 880 x 290 mm and 73 kg, installation requires two people and a solid wall. Through paralleling it can reach 180 kW, so the system grows together with the business.

Output 3/N/PE 220/380 V or 230/400 V, 50/60 Hz, 30 kW / 30 kVA, maximum current 45,6 A / 43,3 A, transformerless topology, power factor above 0,99 adjustable between 0,8 capacitive and 0,8 inductive. PV: 1000 V maximum, 600 V rated, start-up 160 V, 4 MPPT 150-850 V, 8 string inputs, 40 A on each MPPT, up to 60 kW of usable PV power. Two HV lithium-ion battery ports 150-800 V, 70 A and 33 kW per port, backup 30 kW with 1,6x overload for 2 s and switchover under 10 ms. Maximum efficiency 97,8%, European 97,4%, IP66, 530 x 880 x 290 mm, 73 kg, -25...+60 degrees C, CAN, RS485 and Ethernet communication with optional WiFi, cellular or LAN modules, paralleling up to 6 units on-grid and off-grid, warranty 5 years.

Who it suits

Suitable for an office building, a small hall or a farm with a 40-60 kWp installation, that needs backup on all phases and wants two battery banks managed separately.

Terms explained

• Switchover time under 10 ms: The interval in which the installation passes from the grid to the battery; under 10 milliseconds is so short that computers, servers or cash registers do not stop and do not restart.
• Power factor: The measure of how much the delivered current is truly useful to the loads; above 0,99 means almost no useless losses, and the adjustment between 0,8 capacitive and inductive allows the requirements of the grid operator to be met.
• String input: The place where a group of panels connected one after another is connected; eight such inputs mean that the generator can be split over several roof zones.

Technical details

Specifications confirmed from the manufacturer's datasheet

Solis S6-EH3P30K-H belongs to the commercial S6-EH3P(29.9-50)K-H series of three-phase hybrid inverters for high-voltage batteries. The rated AC power is 30 kW, respectively 30 kVA apparent, with three-phase output 3/N/PE at 220/380 V or 230/400 V, 50/60 Hz, and a maximum current of 45,6 A / 43,3 A. The topology is transformerless, and the power factor is above 0,99, adjustable between 0,8 capacitive and 0,8 inductive.

The photovoltaic side accepts up to 60 kW of usable PV power, at a maximum voltage of 1000 V, rated voltage 600 V and start-up from 160 V. The 4 MPPT trackers work over a wide range, 150-850 V, with 8 string inputs in total and 40 A maximum current on each MPPT.

The storage system uses two independently controlled battery ports, for lithium-ion batteries of 150-800 V, with 70 A on each port and 33 kW of charging/discharging power per port. The backup output delivers 30 kW, with an overload of 1,6 times the rated power for 2 seconds and switchover to backup mode in under 10 ms.

The maximum efficiency is 97,8%, and the European one 97,4%. The enclosure has IP66 protection, dimensions of 530 x 880 x 290 mm and a mass of 73 kg, with a thermal range of -25...+60 degrees C. Communication includes CAN, RS485 and Ethernet, with optional WiFi, cellular or LAN modules. Up to 6 units can be paralleled, both on-grid and off-grid. The standard warranty is 5 years.
