What to do if my Victron Energy Controller battery is not fully charged?

E
Emily LeeJul 29, 2025
If your Victron Energy Controller battery is not fully charged, there might be several reasons: * A bad battery connection: Check the battery connection. * Cable losses are too high: Use cables with a larger cross-section. * A large ambient temperature difference between the charger and battery: Make sure that ambient conditions are equal for the charger and battery. * For 24V systems: The wrong system voltage might have been chosen (12V instead of 24V) by the charge controller. In this case, set the controller manually to the required system voltage.

MPPT 100/30

General Description

PV voltage up to 100V

Controller charges batteries from higher voltage PV arrays and auto-adjusts to 12/24V systems.

Ultra-fast Maximum Power Point Tracking (MPPT)

Enhances energy harvest by up to 30% compared to PWM and 10% vs slower MPPT in varying light conditions.

Advanced Maximum Power Point Detection in case of partial shading conditions

SmartSolar algorithm maximizes harvest by locking to the optimum MPP, avoiding local MPPs in shading.

Outstanding conversion efficiency

Achieves over 98% efficiency without a fan, maintaining full output current up to 40°C.

Extensive electronic protection

Includes over-temperature, PV short circuit, reverse polarity, and reverse current protection.

Internal temperature sensor

Compensates absorption and float charge voltages based on internal temperature.

Automatic battery voltage recognition

Automatically adjusts to 12V or 24V systems upon initial setup, manual change possible later.

Flexible charge algorithm

Features a fully programmable algorithm and eight pre-programmed options selectable via a rotary switch.

Adaptive three step charging

Implements a three-step charging process: Bulk, Absorption, and Float for optimal battery care.

Remote on-off

Allows remote control of the controller via a VE.Direct non-inverting cable for on/off functionality.

Configuring and monitoring

Enables configuration and monitoring via Bluetooth Smart or VE.Direct cable using the VictronConnect app.

Installation

General

Mount vertically on non-flammable substrate, close to the battery, ensuring correct ambient conditions for longevity.

Grounding

Details battery grounding configurations and chassis grounding requirements, emphasizing single ground connection.

PV configuration

Explains PV voltage requirements, maximum open circuit voltage, and provides examples for 12V and 24V systems.

Cable connection sequence

Specifies the correct order for connecting the battery first, then the solar array, to prevent damage.

Configuration of the controller

Describes preprogrammed charge algorithms and how to select them using the rotary switch.

LEDs

Explains the LED indicators for regular operation and fault situations, including a binary code for switch position.

Battery charging information

Details default absorption period duration based on battery voltage and user-defined algorithm overrides.

Automatic equalization

Configures automatic equalization settings, its process, and duration limits for different battery types.
