FoxESS H3 Plus 50 to 125 × FoxESS CQ6-L4 to CQ6-L14
FoxESS's CQ6 declaration lists the commercial H3 Plus 50 through 125 inverter models with CQ6-L4 to CQ6-L14 strings. The document permits up to three independent battery strings for H3 Plus, each on its own battery input. Because the permissible range differs from H3 Smart and H3 Pro, the exact inverter family and string size must be checked against the declaration before commissioning.
