Figure 3: Three-phase connection with low tariff signal circuit for CombiWATT mode, or time schedules. Current sensing module is
placed at the facility's supply cable coming from the distribution box where main energy meter is located. The connected loads use only
real surpluses produced by PV-plant. 5 loads are connected, 3 of them through the recommended SSRs, RGS1A series manufactured by
Carlo Gavazzi.
