VICTRON ENERGY SMARTSOLAR MPPT 100/20 Load Output Off

Victron BatteryProtect 65A

The internal load output MOSFETs in the 100/20 are designed for resistive loads and frequently trip on the inrush current of capacitive electronics. This external device handles significantly higher peak currents and allows the MPPT to act as a logic controller rather than a power switch, preventing 'false-positive' short circuit shutdowns. It provides a more robust hardware-based disconnect that is not subject to the internal sensitivity of the MPPT's protection algorithm.

Victron Smart Battery Sense

Incorrect voltage readings due to resistance in the battery leads often cause the MPPT to 'see' a lower voltage than exists at the battery terminals, triggering a premature Low Voltage Disconnect. This sensor communicates real-time, terminal-accurate voltage and temperature data to the MPPT via VE.Smart Networking. This ensures the load output logic is based on actual battery state-of-charge rather than calculated voltage under load, preventing unintended shutdowns.

Automotive Power Relay (12V/40A)

For users requiring simple isolation, an external relay allows the MPPT load output to only provide a small trigger signal to a coil. This removes the thermal and electrical stress from the MPPT's internal solid-state components. By shifting the mechanical switching of the high-current load to an external relay, the system avoids the sensitive 'short-circuit' protection logic that often plagues the 100/20 model when powering devices with high start-up demands.
