Choosing the best off-grid solar system is not easy as off-grid systems are many times more complicated than common grid-connected solar systems. In this article, we highlight some of the many considerations which must be taken into account and discuss the various off-grid system types available. <\/span><\/p>\n

We also explain why a good quality \u2018<\/span>inverter\/charger<\/span>\u2019 is vital to building a reliable off-grid system<\/span><\/p>\n

Basic layout of a DC coupled off-grid system – The most versatile and modular off-grid configuration<\/strong><\/p>\n

Many people believe off-grid solar systems can be easily put together. This may be true in the case of a small caravan or cabin, but in reality, larger off-grid systems used for homes and businesses need to be carefully designed by an experienced solar installer or system designer.<\/span><\/p>\n

Solar and battery storage systems must be installed by an <\/span>experienced licensed electrical professional<\/b>. Modern large scale off-grid solar systems are typically <\/span>high voltage<\/b> and can generate and store huge amounts of energy which can result in damage, fire or serious injury if the installation does not meet all relevant regulations, standards and guidelines.<\/span><\/p>\n

Off Grid System Types (AC or DC coupled)<\/span>\n<\/h2>
Off-grid systems are built using either <\/span>AC or DC coupled<\/span> power sources. AC coupled generation sources include common solar inverters, wind turbines or backup generators (gen-sets), while DC coupled sources include MPPT solar charge controllers<\/span><\/span>\nWhether a system is AC or DC coupled is generally based on the size of the system. Most small-scale systems less than 5kW are DC coupled and use <\/span>solar charge controllers<\/span>.<\/span><\/span>\n\"\"<\/span>\nLarger off-grid systems can be either AC or DC coupled depending on the type of inverter\/charger (multi-mode inverter) used, and the compatibility with different <\/span>solar inverters<\/span> (AC) or solar charge controllers (DC). Most modern multi-mode inverters can be both AC and DC coupled, which creates a very secure, flexible system with multiple charging options.<\/span><\/span>\n<\/div>[\/vc_column][\/vc_row]<\/p>\n

Key considerations when sizing off-grid solar systems<\/span>\n<\/h2>
    \n
  • Daily average energy consumption (kWh) – Summer and winter<\/b><\/li>\n
  • Peak load (kW) – Maximum power drawn from appliances<\/b><\/li>\n
  • Average continuous load (kW)<\/b><\/li>\n
  • Solar exposure – Location, climate, orientation & shading<\/b><\/li>\n
  • Backup power options – During poor weather or shutdown<\/b><\/li>\n<\/ul>\nWith the above considerations in mind the key component of an off-grid power system is the main battery<\/span> inverter\/charger <\/b>often referred to as a <\/span>multi-mode inverter<\/b> as they can usually operate in both off-grid or on-grid modes.<\/span><\/span>\n<\/div>\n
