The standard GRW panel: an automatic mains-failure controller with a 4-pole automatic circuit breaker, all in the segregated control / power / socket cabinet. It runs the set in manual, automatic or remote-start modes and comes with a full scope of protection and instrumentation as standard.

• Controller: Deep Sea DSE7320 MKII (ComAp AMF26-P on some earlier builds up to GRW210P)
• ON/OFF selector switch, analogue fuel level and hour meters, internal voltage-adjust potentiometer
• 5 A battery charger (Deep Sea BC2405)
• Adjustable differential (earth leakage) protection with selector switch (ABB RD3M) – ADI
• 4-pole automatic circuit breaker with thermal and magnetic protection, large busbar with bottom cable entry (ETB), door-open breaker trip (SBT) and breaker status contact (ACB)
• Socket section: two-wire remote start/stop, auxiliary power supply plug, multi-pin connector for a transfer switch (LTS)
• Emergency stop button

Standard on every GRW. Choose ACP or MPP.

A synchronising panel with a 4-pole motorised circuit breaker for running several GRW sets in parallel – the classic events and rental set-up where load grows through the day. The controller handles synchronising, load sharing and breaker control automatically.

• Controller: Deep Sea DSE8920 (ComAp InteliGen NTC + InteliVision 5 on some earlier builds up to GRW210P)
• 4-pole motorised circuit breaker with thermal and magnetic protection, busbar with bottom cable entry, door-open breaker trip and breaker status
• Multi-pin connector for the parallel signal cable
• Same standard scope as ACP: selector switch, fuel and hour gauges, 5 A battery charger, adjustable differential protection, emergency stop

Available from GRW67P (Alfa Plus) upwards. Choose ACP or MPP.

Traditional analogue gauges on the panel for engine oil pressure and coolant temperature, in addition to the readings on the controller.

• Bender ISOMETER IR423-D4-2 or DOLD RN 5897/300, depending on socket kit and stock
• Genset wired as an IT system when IMD is ordered

Replaces the standard adjustable differential protection (ADI). Mandatory with socket kit SPKB6.

• GPS location for asset tracking and geo-fencing
• Connects via USB, RS485, Ethernet or CAN
• Full DSEWebNet access: alarms by email, data logging, reports, iOS/Android app

A DIN-rail gateway that puts the generator on an SNMP network management system, sending traps and emails on alarms and status changes and answering SNMP GET/SET requests.

• SNMP V2, automatic MIB generation
• Customisable email / SNMP trap messages, SMTP client
• Browser configuration, status LEDs, one gateway for multiple controllers

Not combinable with RGW2, RGW9 or ARM7.

Converts the controller's USB port to Ethernet with a built-in web server, so a single set can be monitored and controlled over a LAN/WAN or integrated into a building management system via MODBUS TCP.

• In-built web server, browser configuration
• MODBUS TCP, viewable from four locations at once
• DIN rail mount

Not combinable with RGW2, RGW8 or ARM7.
