13 Load Shedding

AC Power is a limited resource on a boat, even more so when connected to a

shore supply with limited current. Load shedding enables the automated

switching off of predetermined circuits such as water heaters and battery

chargers when the load drawn from the supply exceeds a specified current. This

extra capacity then enables the use of other loads that require immediate use,

such as hair driers.

From version 4.5, N2KView will be equipped with two groups of Load Shedding,

to satisfy the needs of owners with two independent power systems.

Load Shedding requires the optional Control Module to be licensed. (this is

included with all version 4 licenses)

13.1 Sources

Each N2KView Load Shedding group is designed to monitor 4 power sources

simultaneously, typically two generators and two shore supplies. The Load Shed

current is set up individually for each power source, and the Load Shedding

software will try to ensure that the current drawn from each of these sources

does not exceed the current set. Exceeding the current of a Utility (Shore Supply)

will typically trip a breaker, while exceeding the capability of a generator may

damage the generator.

Sources may be Single Phase, Split-Phase, or Three Phase.

Each Source requires a Maretron ACM100 to be connected to report the current

supplied by that source.

For best performance, the ACM100 should be configured as follows, in the

advanced configuration page -

• Damping Period – V, I, F : 100 ms

• NMEA2000 PGN Enable/Disable – Phase A, B, C, and Average Basic

Quantities 500ms

13.2 Loads

N2KView Load Shedding can switch up to 10 loads. Typically the only loads that

one chooses to switch off are water heaters, driers, air conditioners, and battery

chargers, so the limit of 10 loads should not be a limit on most systems.
