Best Victron Charge Controller


Understanding the Victron Charge Controller 

Victron feature a wide range of both MPPT and PWM solar charge controllers. See the BlueSolar and SmartSolar Charge Controller MPPT
The model numbers are what they are, so for example MPPT 75/50, the first number is the maximum PV open circuit voltage. The second number, 50, is the maximum charge current.

Use the Victron MPPT Excel sheet or the Online MPPT Calculator for PV sizing calculations.
For more information about PWM or MPPT charge controllers, read our whitepaper: which solar charge controller: PWM or MPPT?

PWM and MPPT charge controllers are both widely used to charge batteries with solar power. The PWM controller is in essence a switch that connects a solar array to the battery. The result is that the voltage of the array will be pulled down to near that of the battery.

The MPPT controller is more sophisticated (and more expensive): it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement of the battery plus load.

Thus, it essentially decouples the array and battery voltages so that there can be, for example, a 12V battery on one side of the MPPT charge controller and panels wired in series to produce 36V on the other. It is generally accepted that MPPT will outperform PWM in a cold to temperate climate, while both controllers will show approximately the same performance in a subtropical to tropical climate. In this paper the effect of temperature is analyzed in detail, and a quantitative performance comparison of both controller topologies is given.

30amp MPPT Charge Controller – SCC110030210

The 100/30 smartsolar MPPT or 100/30 Victron SmartSolar 12V/24V 30A MPPT controller with Bluetooth is part of the advanced SmartSolar range that employs cutting-edge ultrafast MPPT technology to optimize energy collection while ensuring the battery remains in excellent condition. The BlueSolar 30A MPPT charge controllers are highly regarded for their ability to extend battery lifespan. Additionally, they offer robust communication features for remote system monitoring. This 100/30 smartsolar MPPT 100/30 MPPT Controller is known for its reliability and accuracy.

It come with Ultrafast MPPT Technology:

The 30A MPPT solar charge controller is engineered to maximize energy yield in minimal time, hence the name MPPT. It employs high-speed Maximum Power Point100-30-SMART Tracking technology to monitor the solar panels’ maximum power voltage point, which fluctuates with sunlight intensity and temperature. This ensures continuous tracking and optimal charging.

This technology enables the controller to produce up to 30% greater energy yield than the alternative PWM controllers and as much as 10% more power than slower MPPT controllers. This unique advanced technology allows the controller to perform extremely well in low-light or cloudy conditions. This makes them ideal for the UK. The controller consistently strives to extract the maximum available power from the solar array.

Inbuilt safety protection:

This MPPT Charge Controller is fully equipped with a comprehensive suite of safety features, providing complete protection against hazards like battery reverse polarity, load short circuit, low-voltage load disconnect, and battery overheating, all monitored through an internal temperature sensor. Additionally, the controller boasts advanced self-diagnostic capabilities, pinpointing system errors with precision fault-targeting technology, displayed through high-intensity LED indicators.

Intelligent ‘BatteryLife’ function:

To prevent the battery from completely discharging and to avoid potential permanent damage, this controller includes the Victron BatteryLife feature. This advanced function is intended to prolong the battery’s lifespan by monitoring and managing the output of excessive loads. The controller employs a smart algorithm to persistently monitor the battery’s state of charge and, if necessary (such as during extended periods of bad weather), will incrementally modify the load disconnect threshold to ensure a full 100% recharge is regularly attained each week. Additionally, the load voltage disconnect point can be manually set to a desired level using the VictronConnect software.charge controller

Inbuilt Bluetooth:

This SmartSolar charge controller features built-in Bluetooth which allows the user to easily connect to any Bluetooth enabled device, such as a mobile phone, tablet or iPad in order to access the VictronConnect App This means no additional Bluetooth dongle required. This is a saving over other MPPT Charge Controllers. The mobile app unlocks numerous possibilities for advanced programming and remote monitoring of your Victron SmartSolar system. Once the controller is paired with the app, a wide range of additional features are made available, including:

Firstly – Detailed data logs: System activity for the past 30 days is available to view; either as in-depth daily logs or as a monthly summary. These easy-view graphics display daily energy yield, maximum recorded power and voltage, time spent in each charging stage, minimum and maximum recorded battery voltages, error records and total energy counters.

Secondly – Live data transmission: Real-time information is displayed including solar panel output, battery voltage and current as well as battery state of charge.

Thirdly – Load configuration: Option to choose from one of the pre-set load management programs or create a user-defined program. Includes a streetlight function to control the duration and brightness of nighttime lighting.

The VictronConnect App is also available to download as a PC version, for computers without Bluetooth connectivity. If you would like to use the PC version of the app to monitor/program your SmartSolar system, this controller can be connected to your PC via a VE Direct USB cable.

Optional Remote LCD Display:

The user can connect an optional MPPT Control panel (sold separately) to the controller to access a range of monitoring and programming functions. The display shows charging parameters (voltage, current, power) for the solar panel, battery and load, as well as 30 day performance data. The user can also adjust the load settings and specifically set the duration and voltage of each charging stage.

Other features:

The Victron SmartSolar MPPT 100/30 model is ideal for a wide range of applications as it is resistant to extreme temperatures, high altitudes, dusty environments and marine environments. The unit enclosure is IP43 water resistant with resin encapsulation of the internal electrical components and has a PD3 pollution rating.

This solar charge controller is also compatible with a wide range of battery types, including AGM, GelTubular plate and Lithium batteries.
