Re: This section has the wrong name

Amazed that I didn’t see the word sustainable once in this thread. I guess it’s a synonym for renewable but sort of a little bit more to the point.

I guess I could put it on YouTube but I don’t think I’m ready to take “Robby’s PV TV” live yet :lol:

Re: Inverter with my Solar system make a noise! why?

Here is the shortest clip I have that demonstrates the sound. I occasionally make these how-to videos for new hires & such where I work. This is just part of a longer video explaining how to perform one specific aspect a larger routine maintenance task. I’m essentially having to shout over the noise...

Re: Inverter with my Solar system make a noise! why?

I had to chuckle at this. I work in utility PV and some of those 800-1800kW central inverter’s really can make some seriously loud, annoying noise at high gating intensities.

SMA is a very popular inverter and we’ve joked that it stands for Sound Making Apparatus.

Re: wiring.. before & after

Just spending my Monday evening hanging out on page 20 of the build thread section...Came across this thread about clean wiring. I’m right in the middle of a new build right now and I really prioritized keeping things clean. It has added a significant amount of time to the project but I feel that th...

Re: Kingpan charger voltage adjustment

I’m thinking I should bypass the relay so that there is always voltage on the DC leads. The BMS will open up when the pack is charged...right?

Re: Kingpan charger voltage adjustment

Hello everyone, Even though this thread does not exactly align with my issue I think it provides a good backdrop to what I am experiencing so I chose to bump it, rather than start my own thread. I have a Kingpan KP600E-60L, 50v 10a charger that has begun to give me trouble. It is used to charge a 12...

Re: X-TREME XB-300Li MODS/HACKS/UPGRADES

I bought one of those bikes on Craigslist a few months ago with a dead battery for $125. A friend of mine had gifted me a 12S pack that came with a kranked bike he purchased used and wanted to run the bike on Lipo. The stock controller had absolutely no problem running at 12S and the bike is a real ...

Re: variable regen throttle and controller for ebikes.

I was just looking at this thread earlier this week and suddenly it’s been bumped. Strange coincidence. Anyway I intended to post this relevant link but got busy with something and never did it. Looks like Grin has a variable regen solution: https://www.ebikes.ca/news/CA3-prop-regen/ I think this is...
