- Full network integration without requiring adapters or extra equipment–Modbus and ModbusIP via 485, Ethernet, WiFi, MS-CAN connects MS Devices (proprietary), GS network information bridging.
- WiFi, and Bluetooth connectivity with a mobile device and app for easy connection, dashboard views, downloading data and firmware updates. It also includes our LiveView 2.0 web app interface onboard
- Powerful Load Control – built-in 30A load capability, unique for controllers in this power class
- Oversized PV Array Input capability – array input power rating @ 150% meets today’s system design needs for PV oversizing
- Extensive electronic protections include cold-weather lithium “fold back” circuitry to guard against cold-weather charging damage. Also, short-circuit, over-current and reverse polarity to ensure the controller will not be damaged by wiring mistakes or overloads
- Fanless design for improved efficiency and exceptional long-term reliability
- ReadyBlock expansion system through exclusive ReadyRail design achieves true controller technology integration. All information is instantly available since it’s actually part of the hardware and software of the charge controller itself, instead of outside the system as with a typical stand-alone accessory device. Available ReadyBlock modules include:
- ReadyShunt – battery metering/monitoring, key metrics including state of charge (SOC), energy in/out (Amp hours), current measurement for system sources and loads, and more
- ReadyBMS – full closed-loop communications and control with lithium batteries
- ReadyRelay – signaling (dry contact), advanced load control
