Introducing the Apollo Solar Low Temperature Over-voltage Bypass! (LTOB)
Every PV array can now be sized without being limited by the high open-circuit voltages present at low temperatures. The Apollo Solar LTOB automatically switches modules out of the circuit if the temperature falls below the specified point.
In the graph below, the LTOB removes 1 module from the 6 module string keeping Voc under 140 Vdc. When the temperature falls below 10°C (50°F) the LTOB turns on and the top module is switched out of the circuit so the Voc drops to 120 volts. The 5 module string is below the 140volt limit down to -40°C. When the temperature rises, the LTOB turns off and the module is switched back into the circuit.
Key Features and Benefits: Automatically bypasses PV module at low temperatures to drop Voc. Expand the input voltage range of any Inverter or Charge Controller. Enables an extra PV module in every string. Use with any modules up to 85Voc. Any string voltage up to 600VDC. Switch up to 8 Amps per string. Choice of temperature switch point. Complete safety at the lowest of temperatures without compromising the high temperature performance. Size arrays for maximum power and forget the cold/Voc problem. MC connectors - quick wiring. Sticks to back of any module. Very low power consumption. Failsafe to low voltage output.
