The Inter-Connect System
The Solar Stik System is comprised of three distinct types of technologies:
• Energy storage
• Power management
• Power generation
All of the individual Solar Stik components that operate in these categories utilize a unique
connection architecture, known as the Inter-Connect Circuit.
The Inter-Connect Circuit is the skeletal backbone of the Solar Stik System’s DC power network. It
uses a simple, polarized, locking connection that is common throughout the architecture. All Solar
Stik power management, energy storage, and power generation components are compatible with
the Inter-Connect Circuit.
Using a common, polarized connector allows rapid “Plug & Play” scaling of components, adaptation
of capabilities within the architecture, technology refreshment, and swapping of components when
conditions warrant.
Communicating Voltage
All Solar Stik components on the Inter-Connect Circuit use one value to successfully operate in
concert: battery voltage.
The Inter-Connect Circuit communicates battery voltage to all components on the network, allowing
them to independently coordinate their respective functions. Voltage is used to trigger actions such
as Automatic Generator Start/Stop (AGS) function, renewable power delegation, power distribution
timing, and more.
The Importance of Proper System Connection
While there is no unsafe way to make connections using a common polarized connector, proper
setup of the Inter-Connect Circuit is critical in order to properly communicate voltage to all points in
the System, ensuring all of the components operate together to provide seamless power.
Setup can also directly impact how power is metered in the network. Power management devices
such as Power Hubs and PRO-Verters will meter current as it flows through the circuit, providing
critical real-time and historical data the operator can use to troubleshoot, verify system performance,
and make programming / architectural changes based on evolving conditions. Consult the System
Operator Manual for a connection schematic specific for a particular application.
Circuit Breaker Protections
The Inter-Connect network is protected from overloads and short circuits through a network of circuit
breakers strategically placed throughout the circuit. It ensures the potential for a reverse polarity
connection within the circuit is minimized. If a problem occurs in a leg of the Inter-Connect Circuit,
If the internal temperature of the Power Hub is greater than 104 ºF (40 ºC), the Power Hub
performance will be degraded (See:
Power Hub Internal Temperature Report)
