By Batpred, 1 week ago

  yes, the circuit needs the usual protection, mcb and maybe rcd. then you also need a lockable isolator..   I am 99.99% sure the Solis will do this as required (just best to have the Solis distri...

  @jamespa re when to switch back, you would have to switch back on if the battery was flat! A look out of the window would tell us whether there was any mains to switch to, or it was torch time.  ...

  That makes some sense. I found the Solis was quite open as a manufacturer. I hear some inverters (not sure if givenergy or synergy) leave it all locked to the original installer.   An intelligen...
RE: Help me keep the faith with my air source heat pump installation  

By SimonF, 1 week ago

    I agree and that’s why I don’t believe a lot of the high COPs that get reported on Vaillant units. It’s a shame Vaillant don’t calibrate the sensors. When I had them out to replace mine the Vai...

  Those Manual Changeover switches are inter-locked.For each pair of blue levers, only one can be up (ON) at a time.   I'll return to your diagram later, as I'd like to add a couple of safety point...
RE: ASHP Energy Consumption: Aira 12kW heat pump  

By JamesPa, 1 week ago

  I doubt that matters, ToU tariffs are for the benefit of the grid and electricity suppliers not to aid the transition to EVs. They have been around for decades as a means of load shifting (and thus b...

By ChandyKris, 1 week ago

  Batteries have been a great investment for us. They definitely help us keep the costs under control in the winter. Who knows how long the EV tariffs would last, but with a big push towards EVs it woul...

  I do have some Manual Change switches within my off-grid system. Attachment : AC_changeoverMCB.jpg You can see that the left-hand one allows heating and lighting to be switched back to directly...

By Bash, 1 week ago

    This is why I gave up on the idea of islanding quite quickly. The final straw was potentially having to install an 8ft earth rod in my driveway where all the cables and drain pipes/sewer run. T...

By JamesPa, 1 week ago

  Thats interesting. Are you saying that all of your house circuits are connected to the inverter when it is operating off grid, albeit some of the load has been manually shed? How is this wired? - Li...
