Detailed description

Designed for 12/24V solar systems, the Victron Energy BlueSolar PWM-Light 10A charge controller provides efficient energy management with automatic system voltage detection. This controller uses pulse-width modulation (PWM) to optimize battery charging and improve performance, relying on a multi-stage charging algorithm.

Features and Protections

The BlueSolar PWM-Light 10A includes a load output with low-battery disconnect, plus a lighting control function with a single timer. A two-digit seven-segment display simplifies adjustment of load output features, including the timer. Battery charging occurs in three non-programmable stages: bulk, absorption, and float. Protections include overcurrent on the load output, short circuits, solar panel/battery reverse polarity, and overheating. In case of overcurrent, the system stops after 60 seconds for a 130% load and after 5 seconds for a 160% load. A short circuit causes immediate shutdown.

Technical Specifications

This charge controller supports a nominal charging current of 10A and a maximum solar voltage of 28V for 12V systems (36-cell panels) or 55V for 24V systems (72-cell panels). Standby consumption is less than 10 mA. Absorption voltage is 14.2V for 12V systems and 28.4V for 24V systems, while float voltage is 13.8V (12V) and 27.6V (24V). Low-voltage load disconnect occurs at 11.2V / 22.4V, with automatic reconnect at 13.1V / 26.2V or manual reconnect at 12.6V / 25.2V. The controller operates from -20 to +50°C at full load. It is rated IP20, indicating protection against solid objects larger than 12.5 mm but no water resistance. Dimensions are 70 x 133 x 33.5 mm with a weight of 0.15 kg, and it uses 5 mm² / AWG10 terminals. Wiring is positive common.

Expert opinion

« Analysis of the Victron BlueSolar PWM-Light 10A regulator »

The Victron BlueSolar PWM-Light 10A charge controller is a reliable entry-level solution for small solar installations. Its simple integration and controlled cost make it particularly suitable for applications where budget is a key factor or for low-power standalone systems. Its PWM technology is adequate when the panel voltage is close to the battery voltage, providing efficient and stable charging.

Installation of this controller is straightforward and does not require specialized skills beyond basic electrical knowledge. It must be mounted indoors in a dry, non-flammable environment due to its IP20 protection rating. It must be connected in the correct order: battery first, then solar panel, then load, with the addition of a fuse on the battery’s positive cable. The 5 mm² terminals are suitable for most 10A configurations.

This model stands out for its functional robustness at a very competitive price. It includes all essential protections for system safety: reverse polarity, overloads, short circuits, and overheating. Its use case is clearly oriented toward basic reliability rather than advanced optimization. For more complex systems or those requiring maximum power extraction from solar panels—especially when panel voltages significantly exceed battery voltage—a controller with more advanced optimization technology would be more appropriate. The BlueSolar PWM-Light 10A is therefore a wise choice for a simple and economical "plug-and-play" approach.

Frequently Asked Questions

Need help? Contact us

What is the primary function of the Victron Energy BlueSolar PWM-Light 12/24V-10A charge controller?

The Victron Energy BlueSolar PWM-Light 12/24V-10A charge controller is designed to manage battery charging in 12V or 24V solar systems. It uses pulse-width modulation (PWM) and a three-stage charging algorithm (bulk, absorption, float) to optimize battery performance. It also features a load output with low-battery disconnect and various protections.

What are the charging stages used by this charge controller?

This regulator uses a non-programmable three-stage charging algorithm:

Bulk: Fast-charge phase where maximum current is sent to the battery. Absorption: Voltage is held constant to ensure the battery is fully charged. Float: Voltage is reduced to maintain the battery at full charge without overcharging.

Does the Victron BlueSolar PWM-Light 12/24V-10A charge controller have overload protection?

Yes, the controller is protected against overloads. In case of overload, the system stops after 60 seconds if the load is 130% of the rated current, and after 5 seconds if the load is 160% of the rated current. A short circuit causes immediate shutdown.

What is the self-consumption of the BlueSolar PWM-Light 12/24V-10A charge controller?

The Victron Energy BlueSolar PWM-Light 12/24V-10A charge controller's own consumption is less than 10 mA.

What protections are built into this charge controller?

The Victron Energy BlueSolar PWM-Light 12/24V-10A charge controller includes several protections:

Overload protection on the charge output.Short-circuit protection on the charge output.Reverse polarity protection for solar panels and/or battery.Overheat protection.

How does the low-voltage battery disconnect function work?

The controller automatically disconnects the load when battery voltage reaches 11.2V for a 12V system, or 22.4V for a 24V system, to protect the battery from excessive discharge.

At what voltage is the charge automatically reconnected after a disconnection due to low voltage?

The load is automatically reconnected when the battery voltage reaches 13.1V for a 12V system, or 26.2V for a 24V system. It can also be manually reconnected if the voltage exceeds 12.6V / 25.2V.

Does this controller have a lighting control function?

Yes, the controller includes a lighting control function with a single timer. A two-digit seven-segment display makes it easy to set this feature.

What is the operating temperature range of the BlueSolar PWM-Light 12/24V-10A regulator?

The Victron Energy BlueSolar PWM-Light 12/24V-10A charge controller operates within a temperature range of -20°C to +50°C at full load.

What are the absorption and float voltages for batteries with this regulator?

For a 12V system, the absorption voltage is 14.2V and the float voltage is 13.8V. For a 24V system, the absorption voltage is 28.4V and the float voltage is 27.6V. These voltages are fixed and not user-programmable on this regulator model.

Is this controller compatible with 12 V and 24 V battery systems?

Yes, the Victron Energy BlueSolar PWM-Light 12/24V-10A charge controller is compatible with 12V and 24V battery systems due to automatic system voltage detection.

Which type of solar panels is recommended for this charge controller?

For a 12V system, it is recommended to use 36-cell solar panels. For a 24V system, it is recommended to use 72-cell solar panels, or two 36-cell panels connected in series.

What is the maximum solar voltage this charge controller can handle?

The controller can handle a maximum solar voltage of 28V for a 12V system (using 36-cell panels) and 55V for a 24V system (using 72-cell panels).

Is the regulator compatible with different battery types?

The controller is designed to work with 12V or 24V battery systems. It uses fixed charge voltages (absorption at 14.2V/28.4V and float at 13.8V/27.6V). It is compatible with most lead-acid batteries, but it is recommended to verify that these charge voltages match your battery’s specifications for optimal performance.

What is the maximum recommended cable size for the terminals of this regulator?

The regulator terminals can accommodate cables with a maximum cross-section of 5 mm² (AWG10). It is recommended to use appropriately sized cables to minimize losses, for example 2.5 mm² for 10A.

In what order should the components be connected to the charge controller?

The connection order is critical for a correct and secure installation:

Always connect the batteries to the charge controller first. Then connect the solar panel(s). Finally, connect the load.

Where should the charge controller be installed?

The controller must be installed near the battery, on a vertical surface. The installation environment must be indoors, dry, and non-flammable. It is important to leave space above and below the controller to ensure proper air circulation.

How to check if the battery is correctly connected to the charge controller?

If the battery connection is correct, the battery indicator (green LED) on the charge controller will light up.

What happens if solar panels are connected with reversed polarity?

The controller is protected against reverse polarity connection from solar panels and/or the battery. However, it is still essential to check polarity before connection to avoid any potential issues.
