The stand alone systems or off-grid systems are not connected to the national grid electricity distribution network: all the energy produced is stored and used on site.
They can be: solar, mini-wind or solar and mini-wind mixed.
They are used for energy supply of cabins, boat, camper or isolated areas.
Solar panels should be configured in such a way that they match the DC voltage of the system, which is determined by the battery.
The system voltages are typically, 12V and 24V DC, but some larger systems operate at 48V DC.
The operating voltage of a solar panel in a stand-alone system must be high enough to charge the batteries (for example, a 12V battery 14.4V takes to recharge the battery).
The panel must be able to supply this voltage to the battery taking into account the power loss and voltage drop in the cable controller and battery charger and in conditions in which the solar cells operate at high temperature.
This means that for example solar panel with a Voc of about 20V is necessary to charge a 12V battery.
A charge controller is a fundamental element for stand-alone systems in order to regulate the voltage and/or the current intensity and keep the battery efficient avoiding overloads.
This device adjusts the voltage and current from the solar panels going to the battery. Most of the "12V" panels provide variations between about 16-20 Volts, then, without an adequate regulation, the batteries will be damaged by overcharging.
Most of the batteries require approximately 14 to 14.5 Volts to get the full charges.
Tools for charge controllers, power adapters, remote control, power and modem sensors
Boats, small cabins and portable power stations often have only a few small AC loads. Some may have lighting, a refrigerator and other appliances that do not work in direct current and need alternating current.
Stand-alone inverters act by converting the direct current into alternating current.
Stand alone inverter accessories, box and parallel control and remote control.
Photovoltaic systems with a storage system are designed to increase consumption on-site solar power.
This storage systems are characterized by multiple uses such as they permit to increase on-site energy consumption and at the same time they reduce the dependence on service companies and ensure that electricity will continue to be provided without interruptions
Battery storage systems are used in off-grid systems (stand-alone solutions) to ensure an uninterrupted supply of energy in areas not reached by conventional power grid.
Photovoltaic kit for motorhomes, boats, huts or lighting for every need.
The off-grid photovoltaic system is generally composed of:
All the products to make your camper energy-sufficient and energy-independent.
Here you can find all the accessories suitable for your camper such as photovoltaic panels Kits, cable glands, solar cables, charge controller and others.
All the products to make your boat energetically autonomous!
Here you can find KIT of solar photovoltaic panels, solar cables, cable guides, charge controllers and others.
A solar inverter’s main job is to convert DC power generated from the array into usable AC power. Hybrid inverters go a step further and work with batteries to store excess power as well. This type of system solves issues of renewable energy variability and unreliable grid structures.
