We suggest that you house your inverter along with other power generating equipment in a remotely
sited purpose built area. Also make sure that the exhaust from your generator or other sources of heat or
fumes are kept well away from the SA41. SEIAA (Solar Energy Industries Association Of Australia)
installation guidelines must be followed.
You must have a suitable 48V DC battery bank which is maintained and operated to the battery
manufacturer’s recommendation. To ensure operation to SA41 specification, the battery bank should
have a minimum capacity of 500 ampere hours, at the 100 hour discharge rate (ask your supplier if in
doubt). Smaller capacity batteries can be used but may result in degraded performance of the SA41
under heavy surge conditions.
CONNECTION OF AC AND DC WIRING
IMPORTANT: Before making any wiring connections, check that the circuit breaker located on the
front panel is in the OFF position, i.e. LEVER DOWN.
Your electrician should firstly connect the AC wiring via the three terminal rear junction box. Carefully
observe the correct connections. Please refer to the rear panel view of the SA41 on the following page.
BROWN ACTIVE (red dot, top connector)
GREEN/YELLOW EARTH (E, centre connector)
BLUE NEUTRAL (Bottom connector)
The lid of the junction box has knockouts to allow conduit entry. Make sure the connections are tight
and safe. Re-fit junction box cover.
Verify that the circuit breaker on the front panel is in the OFF position, LEVER DOWN.
