Re: Inverters in parallel to power a house

That makes me even more curious, what did the 'kid' do to overload it? The system got loaded for more than 10kW for more than 20 minutes? That 'kid' must be min...

Re: Inverters in parallel to power a house

Nice setup! :geek: I must say, that is far more compact than I expected. At 30kWh, that is just a tad more compared to 2 x Powerwall-2 in parallel for roughly the same size (considering the gateway requirement as well). Do you mind revealing how much your system cost (just the one in the photo)? I w...

Re: Grounding shielding around motor cable

I'm still confused with 'ground loops'. I thought 'ground loops' only happens when there is a poor ground connection (or long distance wiring). So, when current induces on the cable shield, it will in turn induce current to signal wire. So, if you have good ground (such as car or bike's frame), then...

Echoing what Mike has said. However, without suspension, make it easier if you're a DIY-er though, i.e. long term maintenance.

Mine has run close to 50,000km (over the top details here).
