Growatt THOR 22AS-S

The Growatt THOR 22AS-S is the most powerful version in the THOR range: twice the power of an ordinary three-phase home charger. It is used where the car has to be charged quickly, between two journeys - at a company's premises, in an office car park or at home, if the electrical installation allows it. Like the other S-type models, it has no attached cable: you bring your own and plug it into the socket on the charger.

With 22 kW, a car can receive around 22 kWh in one hour, that is a useful charge during a lunch break or a meeting (an indicative estimate, limited by what the car's on-board charger accepts). The four modes cover the usual situations: Fast for maximum speed, PV Linkage for charging from the surplus of a photovoltaic system, Off-peak for the cheap time slots and Load balancing, which automatically lowers the current when the building is consuming a lot, so that the contracted power is not exceeded. The IP65 enclosure allows indoor or outdoor installation, between -25 and +50 degrees C, with natural cooling and consumption under 8 W at rest. It measures 240 x 380 x 164 mm and weighs 10 kg, it is mounted on a wall or optionally on a pole, and access can be restricted by RFID card when the charger is used by several people.

Supply 400 V AC three-phase, 50/60 Hz, output current 32 A per phase, maximum power 22 kW; Type 2 socket according to IEC 62196-2, cable not included. Protection against overvoltage, undervoltage, overload, short circuit, overtemperature and lightning, internal RCD and 6 mA DC fault current detection. IP65, -25...+50 °C, humidity 5-95% non-condensing, altitude below 2000 m, natural cooling, standby under 8 W, 240 x 380 x 164 mm, 10 kg. LCD screen, indicator LED and emergency stop button; authorisation through the app, Plug&Charge or RFID; Ethernet and Wi-Fi, 4G optional, OCPP 1.6 protocol, optional MID meter; CE certification (LVD and EMC) according to EN 61851-1, EN 61851-22, EN 61000-6-1/-6-3 and IEC 62196.

Who it suits

Suitable for company premises, office car parks and homes with a three-phase connection sized for 32 A per phase, where charging has to be fast.

Terms explained

• 32 A per phase: The maximum current on each of the three phases; the house installation and fuses must be sized for this value.
• On-board charger: The converter in the car that receives the current from the charging station; if it only accepts 11 kW, the car will not charge any faster, no matter what the station offers.
• MID meter: A meter with European metrological approval, optional here, needed when the energy charged has to be billed correctly to someone else.

Technical specifications

Recommended applications

• Fast AC charging at company premises and office car parks
• Homes with a three-phase connection sized for 32 A per phase
• Photovoltaic self-consumption with Growatt inverters, in PV Linkage mode
• Semi-public charging points managed through OCPP 1.6

Technical details

Specifications confirmed from the manufacturer's datasheet

The Growatt THOR 22AS-S-V1 is the maximum-power version in the three-phase THOR range: 400 V AC supply at 50/60 Hz and an output current of 32 A per phase, for a charging power of up to 22 kW. The "S" version has a Type 2 socket (IEC 62196-2) mounted on the station, therefore without a fixed cable - the user connects their own cable, and the station stays clean and protected between sessions.

The included protections are overvoltage, undervoltage, overload, short circuit, overtemperature, lightning protection, internal RCD and 6 mA DC fault current detection. The IP65 enclosure is intended for indoor or outdoor installation, operating between -25 and +50 °C, humidity 5-95% non-condensing, altitude below 2000 m and natural cooling; standby consumption is under 8 W. The station measures 240 x 380 x 164 mm, weighs 10 kg and can be mounted on a wall or on a floor pole (optional).

The interface comprises an LCD screen, an indicator LED and an emergency stop button, and authorisation is done through the app, Plug&Charge or an RFID card. Communication is over Ethernet and Wi-Fi, with optional 4G, and the OCPP 1.6 protocol. The four operating modes - Fast, PV Linkage, Off-peak and Load balancing - allow both fast charging and priority charging from the photovoltaic surplus or in the cheap time slots, with automatic limitation of the current according to the building's load. Optional MID meter. CE certification (LVD and EMC) according to EN 61851-1, EN 61851-22, EN 61000-6-3, EN 61000-6-1 and IEC 62196.
