Notes
1. IMPORTANT: Check the L to N voltage at the point of connection. This must be in
the range 207 to 253V.
2. All wiring and equipment designed must be installed in accordance with the most
recent edition of BS 7671 and must by a qualified Competant Person
3. All calculations assume Ze = 0.35Ω at the point of connection (ie consumer unit).
4. AC Cable between junction box and the consumer board to be sized based on a
total voltage drop not exceeding 1%.
5. Typically a single phase engage cable branch is terminated into a 1-pole 20A Type B MCB
6. The Microinverter uses a HF transformer which provides simple separation. A Type B
RCD is NOT required. A Type AC RCD may be required as a result of the AC circuit
design.
