    DC MCB Not Working?

    Hi all, JFYI I tested this again based on what I learned in this thread, I ran roughly 130A through a single TOMZN 63A single pole and it took 3m30s for it to trip, so seems to be working ok. I think when I get this all wired into my house in August I'll probably switch to JTEC though as these...

    DC MCB Not Working?

    my cells are individually fused so I'll pass on the short circuit, I don't fancy spending the next few weeks checking and refusing 1500 18650's ;) Best I can do is run about 112A through it, its a 63A trip so I'll wait a couple of minutes for the thermal trip.

    DC MCB Not Working?

    aaahh ok, thank v.much for this. It says "Trip type: thermal magnetic" so I guess its the heat type. I'll try it again but for longer.

    DC MCB Not Working?

    Hi All, So I have installed a DC MCB between my battery and my PIP, specifically the "TOMZN" 63A single pole. specs for ref: http://www.generalpower.lk/images/products/DC%20Mini%20Circuit%20Breaker-351a3rb4n0i9c16q7l4bani5ac.pdf Now it said somewhere on the aliexpress listing that the "load"...

    PV wiring when in shade

    Hm yeah that's an idea, though it brings a few other problems. I'd had to run extra PV cabling from inside the house to the roof, there's additional costs of the extra CT's and cabling and lastly it means I wouldn't be able to monitor that circuit with my Solar-Assistant. Yes the shade will...

    PV wiring when in shade

    Think you guys are getting a bit mixed up, the shaded pitched roof panels are facing the road so those are the ones visible from street level. the panels couldn't be raised - they're allowed to be up to 20cm above the highest part of the roof (with chimneys excluded of course :p) and they're...

    PV wiring when in shade

    there isn't really any way the council would know I have them, they're only visible once you're on top of the 3rd floor roof and I imagine I'd have to do something pretty bad to cause them to want to inspect my roof 😅 though I think its fine if they're installed using ballast mounts as this way...

    PV wiring when in shade

    The plot is 140 years old but its not the age that created the law, its because its a terrace row. The law says you're not allowed to make changes to a house that causes it to be structurally deviated from the rest of the terraced plot when viewed from the street level. Hence why during my...

    PV wiring when in shade

    Yeah I'll skip on the MI approach I think, it over complicates and overprices the setup. One other thought I had, the flat roof panels are obviously a bit higher than the lowest unshaded row of pitched panels, they're also likely to be at a different angle - 15 degrees on the flat vs 35 degrees...

    PV wiring when in shade

    Thanks for confirming, I've already emailed MPP to ask them to confirm the MAX series 2x PV inputs actually has 2x CT's behind them. I did think about the MI approach but as you say, this adds a cost of £1400 to my install, and how would you wire the 14x MI 230v outputs to the charger, could...

    PV wiring when in shade

    Hi All, I had a question about the best setup for an array that gets a bit of shade each day - I've done what research I can and believe I know what the best solution would be, but I'd really appreciate your opinions on this. I've made this lovely crude drawing showing my intended array setup...

    WatchPower won't connect to 3024MK PIP

    Hi Guys, I recently purchased an MPP Solar PIP 3024MK directly from them to replace my 3024MSE. My PV wattage had grown so needed a stronger PIP to support it. For some reason I can't get WatchPower to connect? I literally flipped the serial cable over from the old pip to the new one and it...
