Their current sensors should still be rated at 30A AFAIK, but that is a linearity rating the copper should be big enough for more, only the measurement linearity would be worse - easily fixed in software.Īt around the same time I was experimenting with a first prototype of my own design, with the 35A version of the same relays. I didn't have a chance to disassemble one yet. Their new product still uses these kind of relays, but to be fair there now is a 40A version in the same format so I guess (hope) they're using those. Luckily, this triggered the main breaker, but the charger could have caught fire causing a sh*tload of damages.īlack Smoke Of Death this is the upper board that received indirect damage Must have been hot in here Who rated this 32A? SERIOUSLY? So this ticking bomb heated up until THE SOLDER ON A RELAY PIN MELTED and shorted another terminal below. I have no idea how they passed certification. I should have really followed Dave Jones advice here, because if I had tore it apart before turning it on I would have noticed that these f***ers used 30A rated components for their 32A rated product. This company makes beautiful products, with some nice features, but I'm now super pissed at them.
#Redacted se install
Looking for a nicer (and 3-phase) wallbox to install at the office, I stumbled upon. I liked their pilot signal circuit, so I implemented it in my design. it only connects to WiFi, via an ESP8266 - no ethernet and less easy to program if you're not familiar with the platform.the standard box they offer has a very plain look, and the 16x2 display is so 90's.being designed for the USA market, it's only single-phase there are a few workarounds to make it 3-phase, but there are many drawbacks.So of course I built one and was very happy with it! However, there are a few things I dislike about it: This have been the obvious solution for hobbyist in the past. If you can't significantly improve existing designs, why bother? OpenEVSE When building a product, it's important to study the other solutions available on the market, to learn from other's good ideas and mistakes.
