JoJo Water Backup - How is it used?
SilverNodashi replied to Douw G. Gerber's topic in Water Heating & Pumping
You can put a ball valve at the top of the JoJo tank, to automatically top it it up from Municipality, and then run your house directly from the tank. If the water pressure is a bit low, install a 3bar pressure pump -

Yes, you cut the plastic on those tabs away to get a cable in.

I know some companies charge between R2.5 and R4 per Watt.

I can help you, what exactly are you looking for?

Breaking +&- from PV, what to use?
SilverNodashi replied to pvdw22's topic in Fundamentals Of Electricity
In a DC system, it's perfectly fine to "break" just one input. + is normally broken, though - can be broken as well. Solar regulations require that we "break" both though. You need to put fuses in for protection, and then an isolator to safely switch disconnect the PV array from the MPPT in case of emergency. -

But we're already busy fixing it

I think a supercap will last longer?

I prefer to cater for worse case scenario's as well. We can't control, not predict erratic weather and I would rather be safe than sorry in this case.

New solar
SilverNodashi replied to Hamtheman's topic in Starting In Solar? Feel free to introduce yourself
Grid tie inverters, without batteries. do this as well. It will, for example, feed the full 2Kw PV available into the grid. If the house needs 2.5Kw, the remaining 500w will come from the grid. -
And then you need to install a nother R150K solar system to charge it
-
This is quite valuable information. For both the Victron and Voltronic inverters, the manuals state that float voltage should be 53.0V or 53.2V respectively and not 52, or thereabouts as you say.
