Limiter Sensor Automatic Setup
Requires Batteries, AC coupled panels must be off while detecting, and does NOT work for 208V installs.
If you do not have batteries or are in 208V mode: verify CT sensor placement manually.
A. Install limiter sensors as previously described (shown in all diagrams as well). Battery and grid connections also
required before starting auto-setup.
B. Navigate to the "Advanced" Tab of the Basic Setup screen (follow the directions below to get there)
A. Touch the gear icon Touch the Basic Setup button Select the Advanced tab (see Fig. C)
C. Select "Auto detect Home Limit Sensors" and press “OK”
D. Wait for the Sol-Ark to finish its learning process (Sol-Ark will alternate sell back between legs and magnitude
automatically determining the correct settings for the sensors)
E. Verify sensors were correctly configured (see Fig. D) if they are not correct, repeat the learn function
In Limited To Home
Mode HM values will
be close to zero. HM
values should never be
negative. If negative,
the Limiter Sensors are
not installed properly.
Possible Limiter Sensor issues:
Sensors are facing wrong direction
Sensors are on the wrong wire(s)
Sensors are not fully closed on wire(s)
Sensor Polarity is wrong (White = + BLK = -)
Fig. D
Fig. C
Verifying proper sensor direction:
• Any loads in the home will show a positive HM (+) value in Watts
• Turning on solar panels and enabling Grid Sell should show a negative HM (-) in Watts if you are
producing more power than the loads are consuming
• If you turn on limited power to Home mode, then HM: ~0 Watts to zero the meter (system
matches the loads to within 99%)
If you installed limiter sensors (CTs) for Limited To Home selling mode, verifying
the proper sensor placement and direction is critical. Remove one sensor from
the main L1 connection, and the power should drop to 0W.
