Controller training app
he RESOL VBus Touch Trainer is an app that simulates a RESOL controller in real-life operation.
All sensor inputs can be fed with freely adjustable values, all relay outputs are displayed with their A Grid-Flexible Solar Power
System status and pump speed. Users can follow and comprehend functions or try out controller reactions.
For ease of installation, multiple on- Buttons and controls in the app have the same function as in the “real” controllers. All controllers

he inverters can be mounted on solar
racks on the roof where each solar panel
connects to an input channel of the
inverter with MC-4 connectors. Since
there is no high-voltage DC, the system
is safe and easy to install.
Figure 2 illustrates a 3.6KW grid-
lexible solar power system that includes
two 4-channel on-grid solar inverters
and one 4-channel on/of-grid solar
inverter. All three inverters can be
installed on the roof daisy-chained.
Notice that the on-grid AC output wire
of the on/of-grid inverter is daisy-
chained with an on-grid inverter. his
way, only one on-grid AC wire is needed
to run from the roof down and connect
to L1 and L2 of a 20A branch circuit of
the electric service panel. he of-grid
AC output wire from the on/of-grid
in-verter can go through a junction box
and run inside the house to support a
1.2KW of-grid AC circuit to power AC
loads such as lights, fans, TV, computers,
phone-chargers, and a small refrigerator
when the grid is down.
For areas where power outages are
frequent, the on/of-grid inverter can be
installed in-side the garage. Two input
channels of the inverter can connect
to two solar panels on the roof using a
4-conductor DC wire. he other 2 input
channels can connect to a 36V battery SUNCLIX – our tool-free
