Maximize Your Solar Efficiency with Victron's BlueSolar 100/20 MPPT Charge Controller

Important! Programming Your Victron BlueSolar 100/20 for Lithium Batteries

The BlueSolar 100/20 is set to AGM batteries as default, in order to set to lithium you must do one of the following options, all three require an additional purchase:

  1. PC Connection: Utilize a VE.Direct to USB cable to connect the unit to a PC. Once connected, you can program the controller using the VictronConnect software, which offers an intuitive interface and easy navigation.

  2. Smart Device Connection: For programming with a smartphone or tablet, connect a VE.Direct to Bluetooth Dongle to the unit. With this setup, you can use the VictronConnect app for a seamless and convenient programming experience right from your device.

  3. Direct Display Programming: Alternatively, if you prefer hands-on programming, connect a VE.Direct cable from the charge controller to a Victron MPPT control/display. You can then program the unit directly via the display interface, which provides on-the-spot adjustments and settings confirmation.

Exceptional Energy Harvesting with Ultra-Fast MPPT

Harness the power of the sun like never before with Victron BlueSolar 100/20's cutting-edge MPPT technology. Even during fluctuating light conditions, our ultra-fast MPPT advantage ensures you capture up to 30% more energy than with PWM controllers and an additional 10% over other MPPT options.

Victron Energy Limited Warranty Policy

Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the end user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead acid batteries; 2 years from date of purchase by the end user, with a maximum of 30 months from the Victron Energy invoice date, Lithium-ion batteries; 3 years from date of purchase by the end user. In addition to this proof of correct battery usage is required when making a battery warranty claim.

During this period, Victron Energy will, at its option, repair or replace the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation and re‐installation. This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use like:
• Reverse of battery polarity.
• Inadequate connection.
• Mechanical shock or deformation.
• Contact with liquid or oxidation by condensation.
• Use in inappropriate environment (dust, corrosive vapor, humidity, high temperature, biological infestation...).
• Breakage or damage due to lightning.
• Connection terminals and screws destroyed or other damages, like overheat, due to insufficient tightening.
• For any electronical breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state ofthe internal control diode and of the inputs/output X and Y capacitors determine the warranty.

This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone else than Victron Energy or one of its authorized Qualified Service Partners. In order to qualify for the warranty, the product must not be disassembled or modified.

Repair or replacement are our sole remedies and Victron Energy shall not be liable for damages, whether direct, incidental,special, or consequential, even caused by negligence or fault.

Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers in performing warranty repairs and building replacement products. If Victron Energy repairs or replaces a part of a product, its warranty term is not extended. In case of replacement the new component has a warranty of 6 months, without effect on the initial warranty period. All remedies and the measure for damages are limited to the above. Victron Energy shall in no event be liable for consequential, incidental, contingent orspecial damages, even if having been advised of the probability of such damages. Any and all other warranties expressed or implied arising by law, course of dealing, course of performance, usage of trade or otherwise, including but not limited to implied warranties of merchantability and fitness for a particular purpose, are limited in duration to a period of two (2) years from the date of purchase.
