I just bought this on here last week. However, after receiving it and looking over the connections, we realized it will not work with the breaker boxes I have here at my business, without installing a 75KVA Transformer to drop it from 480v to 240v. This inverter is VERY heavy. Used for less than 2 years. Excellent cosmetic and working condition. Solis Inverter is a 40kW 3-phase 480VAC string inverter intended for commercial installations in North America. It has a very wide operating window on each of its (4) MPPT input 300VDC – 800VDC. It is housed in a NEMA 4X enclosure allowing for indoor or outdoor installations. It has an integrated DC disconnect, Max DC input is 1000VDC, maximum # of strings that can be landed internally is 2 + 2 + 2 + 2 = 8 strings. Compact and lightweight design inside a corrosion-resistant NEMA 4X enclosure. Designed for all commercial, industrial and utility scale applications. Transformer-less three phase design with 480Vac output. 98.7% efficient (98.3% CEC) with ultra-low start up voltage. Industry-leading 4 MPPT designs with fast. Integrated Arc Fault Circuit Interrupt (AFCI) option. RS485 Modbus communication protocol with Wi-Fi interface (optional GPRS). 2 x 20Z LCD Display (optional 7 LCD color display). Web based data monitoring with downloadable Solis Web App. Dimensions (inches): 23.4 x 37.2 x 14.4. Inverter Type: String Inverter, 3 phase. Weight(lbs): 147.7.
