1. Safety Instructions

WARNING: HIGH VOLTAGE / ELECTRIC SHOCK HAZARD
Solar panels produce dangerous DC voltages even in low light conditions. Always cover panels with an opaque material during wiring. Never work on the system while panels are exposed to sunlight.

WARNING: REVERSE POLARITY
Connecting the battery or solar input with reversed polarity will permanently damage the unit and void the warranty. Double-check polarity before connecting.

CAUTION: CONNECT BATTERY FIRST
Always connect the battery terminals before connecting the solar panel. The controller detects system voltage (12V/24V/48V) from the battery. Connecting solar first may cause incorrect voltage detection or damage.

Note: The MPPT 75/15 includes a physical Load Output terminal that can disconnect DC loads under low-battery conditions. Do not exceed the 15A load output rating.

LED State	Meaning
Solid Blue (Bulk)	Charging — battery not yet at absorption voltage
Blinking Blue (Absorption)	Charging — absorption phase, tapering current
Slow Blink Blue (Float)	Battery full, maintaining float voltage
Fast Blink Blue	Battery not detected or low battery voltage
Solid Yellow	Over-temperature — reduce ambient temp or solar input
Solid Red	Fault — check VictronConnect app for error code
Short blink + pause	Error code — count blinks (e.g. 2 blinks = battery voltage too high)
