    HBPowerwall (Official)

    I spy a photo of Pete's battery wall (a portion of) in a recent Electronics magazine - Silicon Chip, March 2021 page 21. The article is for a High-Current Battery Balancer build. Up to 4S cascadable.

    REPACK MAKITA 3.0aH WITH MORE CAPACITY

    Anyone figured out how to reset Makitas, and while we're at it - Hitachi/Hikoki? I found a YT video where the guy inserted and removed the battery on the charger a few times, quickly (ie make and brake contact) and he showed that worked. I tried and had no such luck. It perhaps only works with...

    Help me identify this connector please

    5000TL-D. Picked it up for $AUD200. Pulled from a working system apparently. I sent an email to a local PV and DC supplier to see what they could work out. Has the Wifi module and Antenna as well.

    Help me identify this connector please

    I just bought a second hand SamilPower SolarRiver inverter to replace my faulty Macsolar which uses the standard MC4 connectors for the DC string inputs. The SamilPower has very similar connectors but they don't fit. The MC4 pin seems slightly larger, so what are they and where do I get them...

    5kW Solar PV Inverter Brisbane Australia

    My Macsolar is faulty so I'm thinking I'll get a second handy until I decide what hybrid I want. It needs to be at least 5KW and dual tracking / 2 string. It would be great of it had an Ethernet port for grabbing data, but not a deal breaker. Brisbane or Moreton area preferred.

    SUNKKO 709A - Dropped wire

    Long lunch? I'd still like to see if I have it correct if you're able? It only works when the power knob is above about 70% so I've messed something up. I had the opportunity to open up a unit of same model a couple weeks ago but the cuircuit board was completely different and of no help, so...

    I need a bit of advice about replacing cells

    I don't have any Ryobi tools or batteries so I won't be going that route, but thank you. If I did use a tool platform, it'd be Milwaukee as I have a bunch of these that I have recovered from 5Ah to 12Ah. And I have 2 x 12v 100Ah AGM batteries. However, I have more than enough lights for an...

    18650 Projects

    Well I finally have a proper finished project I can post. Its a 10S16P pack made in 2 halves and mounted back to back to make a more manageable item. Powered up the UPS and plugged in my hot melt glue gun for proof of concept and it seems to be working great. My plan is to use it to power my...

    I need a bit of advice about replacing cells

    With the tube full of cells, it'd likely be 2 days lol. I do wonder if they'd get enough current to do a proper job.

    SUNKKO 709A - Dropped wire

    Well it works but I'm not happy with it. I just can't get good welds. Its never been great though.

    SUNKKO 709A - Dropped wire

    I think I have it right. I just had another scope of the board and found broken solder joints at the yellow cap at the top that I had knocked in my efforts to get the board out. Once re-soldered the unit energized. However, after about 3 foot taps, the fuse blew. I had put a 15A in, so that...

    SUNKKO 709A - Dropped wire

    I just tested the foot pedal socket. The left most terminal is open circuit regardless of the foot pedal state. It only closes to another terminal when the pedal is not plugged in, so its just a bypass for the built in welding contacts, to ensure both switches are not active at once. The micro...

    SUNKKO 709A - Dropped wire

    Thanks Bogfoot. I assume you're referring to the pen (pliers). I connected it to the HOT OFF point and it blew a fuse after I pressed the pedal a couple of times. It didn't clunk like it should though, so I think it must go to the foot pedal switch (the left most terminal)... I to was...

    I need a bit of advice about replacing cells

    You gotta be shi&@ting me! I bought a pack of 2 'Click' branded tube lights from Bunnings a few years ago when they were on clearance, and from your pics, the housing looks identical with a different circuit board. Took one camping a couple of times, and the light output is great for a gazebo...

    SUNKKO 709A - Dropped wire

    OOPS. I'm modding my Spot Welder for better performance and cooling. I've removed the gantry behind the front panel and used the wires to double the current capacity to the pen. In the meantime, I've dropped a wire to the main board - the small red one from the front of the transformer. Anyone...
