Complete photovoltaic set dedicated to use in motorhomes, boats, summer houses, campsites, mobile units and places.

Description

The solar system consisting of a flexible 150W ETFE monocrystalline module and the MPPT Lumiax 20A Bluetooth charge controller. An efficient motorhome power supply system, used in larger campers, caravans and boats. A typical set, thanks to which we can freely use appliances (12V) such as LED TV, LED lighting, chargers, compressor refrigerators with a thermostat, etc. for several hours a day.

The kit includes:

• SUNBANK 150W 12V ETFE flexible panel
• 20A Lumiax Win500 MPPT regulator
• Set of solar cables (2 x 5m, 1x4mm) with connectors
• Set of battery cables
• OPTIONAL > SIKA adhesive kit

Flexible photovoltaic module

SUNBANK 150W monocrystalline ETFE flexible panel shows excellent electrical and structural properties. Its dimensions, shape and flexible design make it achieve its efficiency when mounted on any type of surface. The dark-colored surface of the panel allows it to better absorb sunlight and return the stored energy more efficient.

MPPT charge controller

A solar charger collects energy from photovoltaic panels and stores it in batteries. Thanks to the use of the latest and fastest technology, the MPPT SmartSolar charger maximizes the amount of accumulated energy and sends it intelligently to fully charge the batteries in the shortest possible time. SmartSolar keeps the battery in good condition, extending its life.

The MPPT SmartSolar charge controller allows you to recharge even a badly depleted battery. Works already at zero battery voltage, provided the cells are not permanently sulphated or otherwise damaged.

MPPT vs PWM

MPPT (Maximum Power Point Tracking) regulators optimize the voltage from the solar panels so that the batteries receive the maximum amount of energy. The maximum power point or optimum conversion voltage varies with changes in light intensity, temperature, and other factors. The digital optimization process performed by the MPPT controller quickly finds and adapts to the maximum power point thanks to advanced electronics, microprocessor circuits and complex work algorithms which explains their high price in relation to PWM controllers. MPPT regulators have an efficiency of 93-97% in converting power from a solar panel.

PWM (Pulse-Width Modulation) controllers are significantly cheaper than MPPT controllers, but they have losses of power conversion from the solar panel up to 60%. This is because PWM controllers do not optimize the voltage flowing to the battery, making them a poor choice for larger panels, but with smaller systems the price significantly affects their choice.
