USE SURPLUS SOLAR ENERGY TO HEAT WATER
Batteries are usually full by mid-day; the rest is discarded. Use that excess energy to heat your water.
When the batteries are more than 80% charged and the water less than 42°C the controller turns on the replacement 12 or 24v heater element in your boiler. Switches off at 53°C. Only restarts when batteries again fully charged
Have a hot shower,
Do the dishes whenever you like.
Only needs 300w of solar power & 300Ah of domestic batteries.
The standard kit product includes the GREEN YACHTING controller unit and a 12, 24, or 48v Quick or Isotherm 300w water heating element that replaces the one currently installed in your boiler. (Isotherm/Webasto 12v only).
There are LED status lights on the controller - green when connected and on standby; red when providing power to the heating element.
Not supplied: the fuse/switch; negative bus bar; cabling; connectors.
The enhanced kit product includes the controller unit, a remote monitor panel that also acts as fuse/switch, and a 12, 24, or 48v Quick 300w water heating element that replaces the one currently installed in your boiler. (Isotherm is 12v only).
There are LED status lights on the both the controller unit and on the remote - green when connected and on standby; red when providing power to the heating element.
Having the remote display that also acts as a matched switch/fuse is a big advantage. You can see the system status at all times without having to dive into the boiler compartment.
Not supplied: negative bus bar; cabling; connectors.
In the summer months, your batteries are usually fully charged by mid-day and the rest of the time, the solar energy is being discarded. We use that surplus energy to heat the water in your boiler. No need to run the engine or be connected to shore power.
Most of the time it is just a question of "topping up" the water temperature, so power consumption is much less than you might expect, and the cut-off point is higher than that of the fridge for example, so essential equipment does not get switched off by accident, and the beers stay cold.
Even if you have a generator on board, you save fuel and noise pollution with the Green Yachting Solar Energy Recovery System.
Install it and forget it! Hot water from the sun, FREE, all the time!
