If you're looking for the best smart method of maximising your on-site consumption of excess solar PV generation, you can now stop looking, as you've found it. 

Immersun unit

The Immersun unit constantly monitors the exported electricity levels, and diverts this excess generation to up to 2 different circuits in series controlling 1 or more Immersion heaters in your hot water tank, and potentially other circuits such as dish washer and washing machines depending on the make, model and wiring arrangements.

Immersun limits the power being fedto each circuit. This ensures that it will never draw more than the excess PV generation, and will automatically reduce or stop this power level any time that consumption elsewhere in the house increases.

Energy generated and exported with Immersun fitted

Its built-in timer will ensure that your hot water is automatically heated to a safe temperature thus avoiding the potential build up of Legionella that can happen with other less smart models, or to ensure that your dish washer cycle is always finished by the time you arrive home.
