The Acrel DTSD1352 is a three-phase energy meter that Solis lists as a supported meter for its three-phase grid-tied inverters. It comes in two versions: an inline 80 A version for sites under 40 kW, and a version that uses external CTs with a 5 A secondary. Connected to a compatible Solis inverter, the meter supports the inverter's internal export power limit and consumption monitoring. Examples are the S5-GR3P, S5-GC and S6-GC3P series. Larger S6-GC models use 300 A CTs. The meter ships with three Acrel AKH-.66 K24 150A:5A CTs, so the CT ratio should be 30, which is primary current divided by secondary current. Change the ratio if you use other 5 A CTs. If the meter readings do not match the actual loads, check the CT ratio. You set it through the In and CT menus and must save it on the Save screen, or the change is lost. The sources give different setup codes: one gives an initial password of 0001, another says to enter 0008. For a three-phase three-wire LV network, set the wiring system to 3P3L in the PL screen of the SYS menu, then save.

sec=h1 h=0caa9c940137review note: support check: partial - S6-EH1P(3-8)K-PLUS is listed under the external CT DTSD1352 entry 'when parallel', but the 'only' and 5A-version phrasing is inferred; the entry lists the DTSD1352 with 5A CT secondary, which broadly fits.
