MPPT solar laadregelaar Victron Energy BlueSolar 100/15 — 15A, 100V max PV

Victron Energy BlueSolar MPPT 100/15 is a Maximum Power Point Tracking solar charge controller engineered for efficient battery charging from photovoltaic (PV) arrays. Rated for 15 A charging current and compatible with PV open-circuit voltages up to 100 V, this compact controller optimizes energy harvest from small to medium PV installations used in off-grid systems, marine applications and recreational vehicles. It supports multiple battery chemistries and programmable charging profiles to maintain battery health while preventing overcharge, reverse current flow and damage from excessive PV voltage.

Advantages

The BlueSolar MPPT 100/15 improves conversion efficiency compared with PWM controllers by continuously tracking the PV array’s maximum power point, which increases daily energy yield in varied sunlight conditions. Its 100 V PV input capability allows use with higher-voltage panels or strings, reducing system wiring complexity. Built-in protections include over-voltage and reverse current prevention, and the unit offers configurable charge algorithms to match different battery types, enhancing lifetime and reliability of the battery bank.

Suitable for

• Small off-grid solar systems for cabins and remote power
• Marine installations on boats and yachts
• Campervans, motorhomes and RV power systems
• Supplementing grid-tied or hybrid systems with battery storage where a compact MPPT is needed

Key specifications

• Maximum charge current: 15 A
• Maximum PV open-circuit voltage: 100 V
• MPPT (Maximum Power Point Tracking) conversion for improved energy harvest
• Programmable charging profiles for different battery chemistries (e.g., lead-acid, AGM, gel, lithium—refer to manufacturer documentation for supported profiles)
• Integrated protection: over-voltage protection, reverse current prevention and thermal regulation
• Compact form factor suitable for installation in small enclosures or on-board vehicles

How to use

Install the MPPT controller following safe electrical practices and the manufacturer’s installation guide, mounting the unit in a dry, ventilated location away from direct heat sources. Connect the battery first, observing correct polarity, then connect the PV array ensuring the open-circuit voltage does not exceed 100 V. Configure the charge algorithm and battery settings according to the battery manufacturer’s specifications using the device interface or compatible monitoring tools. Monitor charging status and system voltages regularly to ensure correct operation.

Recommendations

To maximize performance and battery life, use appropriately sized PV panels and wiring, keep cable runs short, and match the controller’s charge profile to the battery type. Periodically check connections for corrosion and ensure adequate ventilation to prevent thermal shutdown. For systems requiring remote monitoring or advanced settings, pair the controller with compatible Victron communication accessories.
