NRS-097-2-1 Certified

This product must be installed by a qualified electrician/technician. All installations must adhere to local wiring regulations and standards. ClearRay Solar will not be held liable for any product malfunctions as a result of incorrectly installed systems.

Important

Please note that this inverter does not include a data logger, CT, meter or export power manager. The meter "SOL-METER-3PH-CT3" is needed for export power control of one inverter, for more than one inverter use the EPM3-5G-PLUS. The meter requires a data logging stick but EPM3-5G-PLUS has a built in data logger. These items are sold separately.

8 kW at a glance

12 kWPV maximum
98.5%Max efficiency
11.5 APer phase, rated
180 VStart-up

A mid-size three-phase inverter for larger houses, farm buildings and workshops. Up to 12 kW of panels, still a G98 connection.

String design

There are two independent MPPTs, 16 A and one string each, with a 20 A short-circuit rating. Tracking covers 160–1,000 V and the input limit is 1,100 V. Two roof faces or ground rows can each have their own string. Twenty-four 500 W panels, twelve per tracker, fill the 12 kW recommendation.

Built in vs separate

  • DC switch in the inverter
  • Surge protection (Type II) for DC and AC
  • Integrated AFCI, activation required
  • Export control: a meter for one inverter
  • Data logger (not supplied)

Grid connection

G98 still applies at 8 kW

Rated output of 11.5 A per phase keeps it under the 16 A per-phase limit (11.04 kW over three phases). The G98 certificate is in the Documents tab.

Your questions

Can the two strings face different directions?

Yes, each has its own tracker, so an east and a west string are optimised separately.

What maximum AC current should the circuit handle?

12.7 A per phase.

Will it work on a standard UK three-phase supply?

Yes. The datasheet lists 3/N/PE at 230/400 V, as well as 220/380 V.

How is the 8 kW sold in bulk?

Packs of 3 and 6 of the S5-GR3P8K. Per-unit pricing is shown in the table below.
