Before mounting, check that the cable you clamp fits within the 100 A CT diameter: this will ensure correct self-consumption readings from the first start-up.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0260\/6222\/5485\/files\/Chi_siamo_oniroview.jpg?v=1751647335\" style=\"width: 100px; height: 100px; object-fit: cover; border-radius: 50%; border: 2px solid #1e3a8a; flex-shrink: 0;\" alt=\"Esperto Oniroview\"\u003e\n\n\u003c\/div\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Solax M1-40 Meter compatible with my inverter?\u003c\/strong\u003e\u003cbr\u003e\nThe M1-40 communicates via RS485 and works with Solax inverters that support external single-phase meter connection.

The choice depends on your system configuration: single-phase for standard domestic users, three-phase for three-phase systems. Accuracy and 50 ms refresh rate are identical on both models.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use a CT other than 100 A?\u003c\/strong\u003e\u003cbr\u003e\nYes. The M1-40 works with CTs with 40 mA output in different capacities: in addition to 100 A, Solax offers 200, 400, 600, 1000, 1500, and 2000 A. Choose the capacity based on the maximum current of the cable to be measured.
