1. General Description 1.1 PV voltage up to 100V The charge controller is able to charge a lower nominal-voltage battery from a higher nominal voltage PV array. The controller will automatically adjust to a 12 or 24V nominal battery voltage. 1.2 Ultra-fast Maximum Power Point Tracking (MPPT) Especially in case of a clouded sky, when light intensity is changing continuously, an ultra fast MPPT controller will...

1.8 Flexible charge algorithm Fully programmable charge algorithm, and eight preprogrammed algorithms, selectable with a rotary switch. 1.9 Adaptive three step charging The Controller is configured for a three step charging process: Bulk – Absorption – Float. 1.9.1. Bulk During this stage the controller delivers as much charge current as possible to rapidly recharge the batteries.

1.11 Configuring and monitoring - Bluetooth Smart (built-in): connect to a smartphone or tablet running iOS or Android. - Use the VE.Direct to USB cable (ASS030530000) to connect to a PC, a smartphone with Android and USB On-The-Go support (requires additional USB OTG cable). - Use a VE.Direct to VE.Direct cable to connect to a MPPT Control, a Color Control panel or a Venus GX.
2. Safety instructions SAVE THESE INSTRUCTIONS - This manual contains important instructions that shall be followed during installation and maintenance. Danger of explosion from sparking Danger of electric shock Please read this manual carefully before the product is installed and put into use. This product is designed and tested in accordance with international standards.
3. Installation WARNING: DC (PV) INPUT NOT ISOLATED FROM BATTERY CIRCUIT. CAUTION: FOR PROPER TEMPERATURE COMPENSATION THE AMBIENT CONDITION FOR CHARGER AND BATTERY MUST BE WITHIN 5°C, 3.1. General Mount vertically on a non-flammable substrate, with the power terminals facing downwards. Mount close to the battery, but never directly above the battery (in order to prevent damage due to gassing of the battery).

WARNING: WHEN A GROUND FAULT IS INDICATED, BATTERY TERMINALS AND CONNECTED CIRCUITS MAY BE UNGROUNDED AND HAZARDOUS. (also see the MPPT Excel sheet on 3.3 PV configuration our website) Provide a means to disconnect all current-carrying conductors of a photovoltaic power source from all other conductors in a building or other structure.

3.7 Battery charging information The charge controller starts a new charge cycle every morning, when the sun starts shining. Default setting: The maximum duration of the absorption period is determined by the battery voltage measured just before the solar charger starts up in the morning: Battery voltage Vb (@start- Maximum absorption time...

3.8 Automatic equalization Automatic equalization is default set to ‘OFF’. With the Victron Connect app (see sect 1.10) this setting can be configured with a number between 1 (every day) and 250 (once every 250 days). When automatic equalization is active, the absorption charge will be followed by a voltage limited constant current period.
4. Troubleshooting Problem Possible cause Solution Reversed PV connection Connect PV correctly Charger does not function Reverse battery Non replacable fuse blown. connection Return to VE for repair Check battery A bad battery connection connection Cable losses too high Use cables with larger cross section Large ambient Make sure that...
