mppt solar charge controllers - Advaned & Efficient mppt regulator

In cases of shading or clouded sky, when light intensity is changing continuously, a fast Maximum Power Point Tracking (MPPT) algorithm will improve energy harvest by 10 to 30% compared to Pulse Width Modulation (PWM) charge controllers.

Brands

Votronic (Made in Germany)

Votronic MPPT controller have duo charge outputs:

1) Main charging output to Main/House Battery,

2) 2nd charging output trickle charges vehicle start battery. Multi-stage charging profile can be set by user to four different types of battery.

An optional remote LCD display provides precise reading of solar charging current, battery voltage, power and the Amp-hrs and the Watt-hrs (Solar Computer S).

When choosing a model, select the closest wattage, i.e. if using a 200W panel, you can select either the 165W or 250W model. Ensure your panel Voc does not exceed 50.

Genasun (Made in USA)

Genasun’s robust product line, made in the USA, has no moving components so there are no fans to get clogged with dust and dirt, or relays that will eventually stop switching.

These state of the art controllers keep your lithium or lead acid batteries topped up in even the harshest climates, and the Class I Division 2 classification means even hazardous environmental conditions won't stand in the way of keeping your systems running. The products deal with extreme environmental conditions with temperature range -40^oto +85^oC.

The GVB (Boost) series can take a standard 12V solar panel and boost the voltage to charge a 24V, 36V or 48V battery pack.

IP68 Waterproof options available

To select a Genasun model, divide the panel watts by the battery voltage, i.e. 120W / 12V = 10A. Therefore select the model closest to 10A, i.e. the 10.5A model. Ensure your panel Voc does not exceed 27.

Victron

Humidity protected, these advanced MPPTs include Advanced Maximum Power Point Detection in case of partial shading conditions.

The Victron SmartSolar range have built-in Bluetooth for remote monitoring and control by utilising the free VictronConnect app. Many parameters can be viewed and set, such as battery voltage, solar history, load output, flexible battery charge algorithms plus day/night timing and light dimming options.

The Victron BlueSolar range does not have bluetooth built-in. You need for a VE.Direct to USB interface or VE.Direct Bluetooth Smart dongle to use the free VictronConnect software or app.

When choosing a Victron model, for example MPPT 75/15, the first number is the maximum PV open circuit voltage (Voc) and the second number, 15, is the maximum charge current (Amps).
