IMPORTANT SAFETY INFORMATION:
WARNING:
Shock Hazard
The Morningstar GenStar MPPT must be installed
by a qualified technician in accordance with the electrical
regulations of the installation location.
WARNING:
Shock Hazard
This unit is not provided with a GFDI device. This
charge controller must be used with an external GFDI

DC relay dry contact hardware functionality and firmware
control and logic to the Morningstar GenStar MPPT
charge controller.
ReadyShunt (RB-Shunt-1)
The ReadyShunt is an expansion block designed to
display measured branch currents, count Amp-hours for
those branches, and allow net maximum charge current
into a battery, but not exceeding the battery’s maximum
charging rate.
ReadyBMS (RB-BMS-1)
The ReadyBMS provides simple visibility of battery
performance, hands-free settings and optimized battery
