How to connect ?

The order of steps is extremely important!

Example of an stadard grid-connected photovoltaic installation and surge protection. A photovoltaic solar system connected to a switchboard (home/factory...) allows the use of solar energy from a photovoltaic power plant for their own needs (home / office / factory). The excess of PV electricity will be sent to the grid. The "Zero Export" inverters works this same way, but without exporting electricity to the grid.

Thermal solar system - for warm water/buffer/pools heating

Diagrams
 

Basic System Components:

• Solar Collector
• Heater/Buffer (heater for warm water, buffer for home heating)
• Solar Group (incl. controller, circulation pump, screws connectors)
• Extension Vessel (dedicated for thermal solar systems)
• Solar Fluid (polypropylene safe glycol 20-30L)
• Mounting construction + pipes

Optionally recommended: other system heating source (gas heater, heat pomp, etc...)

Two sections (on roof)

Memo: with additional solar pump and external heating source.

The Solar Group controls 2 independent solar pumps. 

Separate heater and buffer

For warm water and bufer for supporting home heating.

Memo: with additional solar pump and external heating source.

The Solar Group controls 2 independent solar pumps and 1 additional for circulation (in sum 3 pomps can be independently controlled).

Buffer tank with integrated warm water heater (one unit - heater in buffer system - 2in1)

If possibile we recommend to use two separate independent tanks, one for warm water and second for home heating (buffer).

Memo: with additional external heating source and floor-heating system connected to the buffer.

Buffer tank with integrated warm water heater (one unit - heater in buffer system - 2in1) and additional pool heating exchanger.

If possibile we recommend to use two separate independent tanks, one for warm water and second for home heating (buffer).

Memo: with additional external heating source and floor-heating system connected to the buffer.

Standard pool solar thermal heating system.
