Off-Grid Systems

The ticket to the world of energy independence!

Without the ability to connect you can get 100% independence

OFF-GRID power plants are suitable for objects without the possibility of connection to the grid; such as caravans, cottages etc. The power output ranges from hundreds of watts to hundreds of kilowatts. Installations are also suitable if you want to ensure reliable supplies of tens kWh in insular premises of industrial production and also if you want to be 100% independent from the distribution network.

Are you interested in OFF-GRID installations?

Do not hesitate to contact us by filling in our form. Our team of professional and experienced solar panel installers is more than happy to discuss and analyse your needs. Please get in touch with us if you are interested in the hybrid application. We recommend you answer following questions prior having a consultation with us:

  • What kind of appliances are you using / will you be using?
  • What is the total maximum output of your appliances?
  • How often are you using particular appliances in given days / months / season?
  • What kind of appliances can you purchase and use with direct current power supply?
  • How user-friendly appliances do you want? How much do you want to look after them? How much can you accommodate?
  • Can you use other alternative energy sources, e.g. oil, petro, wind, water, gas, wood?
  • How much money and how long are you planning to operate the OFF-GRID installa­tion for?
  • What kind of savings (e.g. money, time, climate, noise, CO2) do you expect from the system?

Please read below if you want more information about the OFF-GRID system.

A proposal for the off-grid system!

This system is ranked among the most complex projects in the area of photovoltaic sources. In Europe it is necessary to take into consideration the changing weather and therefore also the alternative or emergency sources of energy. Significant if not a key part of the OFF-GRID system consists of batteries for the energy accumulation / storage for later use. Almost on a daily basis we provide a service to incorrectly configured OFF-GRID plants, completely unsuitable cheap batteries which can not operable any more after a year of usage. It is not worth saving money on these applications.

The components of insular installations consist of optimally designed types and quantity of photovoltaic panels, wind turbines, inverters, chargers, battery systems and so-called insular inverter (the electricity generator). The components are suitable for a wide range of applications. The energy can be supplied to family houses, telecommunication stations, holiday cottages, weekend houses, boats and houseboats with a remote or expensive access to the grid. The intelligent management of energy production and consumption optimally utilizes resources (inverters and batteries) and thus ensures a greater battery life and the whole OFF-GRID system life. Due to a robust construction of individual components, the installations can be operated even in extreme climatic conditions. This ensures a reliable supply of electricity during all seasons and times wherever it is needed.

The main component of the OFF-GRID system pack

It is so called OFF-GRID inverter which enables to produce the alternating current at a standard voltage of 230 V. It is also responsible for the regulation and charging batteries via a standard inverter and it controls the additional optional diesel generator in case of emergency. The optimal efficiency and effectiveness is achieved by a correct design of power plants and batteries capacity. The most sensitive part of the installation and often also the most expensive, is the accumulation of energy in the batteries to provide power at night or on days without sunshine.

Features overview

  • Installed capacity of top photovoltaic panels from 500Wp to 2MWp
  • The capacity of batteries from 2kWh to 200kWh of electricity
  • Usage of battery technology AGM/GEL/LiFEY4PO/LIT­HIUM-ION
  • Single-phase and three-phase solution
  • Tailored solution exactly according to customer’s needs and location

Who is suitable for this product?

  • Caravan owners

  • Boat / ship owners

  • Cottage and farm-house owners

  • Replacement or replenishment of current diesel stations or objects which are dependant on the electric switchboard
