Delta solar inverter models RPI M30A and RPI M50A are now SunSpec Certified™

The Delta models conform to the SunSpec Alliance™ defined communication protocol.

The open protocol is increasingly becoming the standard for information exchange between system components and control systems in solar PV and energy storage installations.

Delta’s communication solution is based on Modbus RTU, and is therefore ideally suited for all PV plants, even utility-scale PV installations.

The robust industrial solution allows communication distances of up to 1,200 meters without the need of additional components such as hubs or repeaters and without the introduction of electromagnetic pollution to the local environment.
