OFF-GRID SOLAR SYSTEM DESIGN 

Off-grid solar system calculator

• Based on the information provided by the Victorian government, typical energy consumption, we designed off-grid solar system packages. Every off-grid solar system is designed in such a way that you are very unlikely to need to use a backup generator or grid. We have many off-grid systems installed without generators. The most important part in any solar energy system is a solar generation power. The Ingeteam off-grid inverter is one of the best solutions as it allows connection of up to 15kW of panels. See below the recommended system sizes by household.

Innovation in off-grid solar

The most advanced off-grid solar inverter is from Ingeteam. A very powerful inverter provides 6kW and continues power in high ambient temperatures like 40°C. Normally off-grid solar inverters heavily derate power output at a higher temperature.
This off-grid inverter can build a powerful battery charge. The inverter can also be connected to the grid or generator. Ingeteam also provides a free comprehensive online solar monitoring system. 

Our choice of solar panels for off-grid solar installations

o Most of our off-grid solar installations have been done with popular solar panels brands like TrinaSolar, Jinko or Suntech. For a person who is looking for a premium product, we have the right choice of solar panels from LG, REC, Q-CELLS or Sunpower solar panels manufactures. We install Tigo power optimisers to improve solar energy system performance in partly shaded conditions.

DC or AC coupled off-grid solar

The off-grid solar system is usually installed in Dc or AC coupled systems. Dc coupled systems are used when solar panels are connected to the batteries via a charge controller first. The Battery inverter takes energy from the batteries and converts it to the AC. In an AC coupled system, the battery inverter become a battery charger as panels are connected to a grid inverter.

The Ingeteam off-grid inverter is made as one system combining all functions in one. The Ingeteam is a DC coupled system but is managed by one device most efficiently. This system is capable of working off the grid without batteries.

Solar energy storage for off-grid solar

Solar energy storage solutions may be sourced from one of the biggest manufacturers in the world. The high voltage lithium solar battery from Pylontech is a very flexible solution. An off-grid solar system can be built with only 3 batteries and extended later if needed. This solar battery system is warranted for 7 years and allows 90% depth of discharge (DOD90%).Power cube brochure

AC and DC coupled off-grid solar system

We can still offer several old types of off-grid solar systems. We can conduct long-term installing of massive and low-efficiency off-grid systems like Selectronic with Fronius or Schnider transformer off-grid solar system and Victron off-grid solar systems.

Off grid solar system with generator

o The generator used to be an essential part of off-grid solar systems. The cost of solar panels and batteries were extremely high and the use of a generator was a necessity. Throughout the last ten years, the cost of solar panels and solar batteries fallen dramatically and it has become possible to build an off-grid solar system which does not rely on a generator. Oversized solar panels arrays and large battery banks allow some families not to have generators at all.
