Hello all, and thanks in advance for your help. My customer has a boat with two Multiplus 12/3000/120v, arranged for split phase operation (120v/240v).
The boat is setup for 50 amp service, although currently at its home marina it is limited to 30 amps, due to using a ‘Reverse Y Splitter’ connector, using two 30 amp 120v outlets to get 240v.
The problem is that there are some 240v loads that do not pass through the inverter, mainly the washer and dryer. The Multiplus cannot see these loads, so the input current limiter does not work as intended. The main result being that when using the dryer and the house bank needs charged, the shore power pedestal breaker keeps getting tripped. Not ideal.
I’ve found that a AC Current Sensor could be installed on each phase, and connected to the relevant Multiplus. It is not clear from the documentation whether the inverter will use that data when calculating the input current limit.
Would a pair of AC Current Sensors solve this problem, or are they only for measuring PV input to the system?
Thank you!
