    AC DC circuit breaker confusion

    I have a 12v 280AH lead-acid tall tubular deep cycle batter and connected to the 12v 2500w (surge up to 5000w but rated actual power is 2500w) inverter. I want to install a circuit breaker between battery and the inverter. One shop suggested me a 80A breaker which seems to be AC-DC (picture...

    Dc shunt motor running of PV direct, no batteries....advice needed please

    Great! I love the idea of battery less systems. I am designing a fridge to run during the daytime from solar panels. Basically, I plan to convert an AC fridge into the DC. I am struggling with how and what to add such that on certain conditions (cloud, evening start) fridge automatically stops...

    12v DC motors

    Hey mates. I recently came across some 12v DC motors. The one I have right now is 12v takes 12A on load (installed in screw pump to lift water from underground tank to the upper tank). The new motor that I came across a scrap shop was said to be 500 watts. Can I replace my 12v 12 amps motor...

    Placement of bypass diodes

    You exactly got me right. I, too, was discussing this based on YouTube video of Amy. I didn't know she has passed away. May her soul rest in peace, amen. I got the idea that what she meant was adding a bypass diode to bypass an entire solar panel. Picture shared by Hedges seems to correspond to...

    Placement of bypass diodes

    Thanks so much. I shall try this. I shall try to post a picture from the junction box which is too cheaply built. Brass sheets instead of copper and diodes quality is poor. I need to solder the replacement diodes and wires coming out of the panel, but that's another issue. I bought a 200w...

    Makes sense. Thanks.

    Placement of bypass diodes

    Greetings Hedges. You got my concern spot-on. Thanks for understanding. Seems that the panels I have experienced are poor quality (I got the news of rejected lot panels being sold from China and then resold as fresh stock by some resellers). If the picture by mopat is correct, then why the...

    Reverse Bias due to shading and Bypass Diodes

    Thanks a lot. I am very confused since, in my experience, shading on one panel connected in series with other panels of similar configuration, shuts down the entire system. This doesn't happen in parallel connection though. However, my inverter is designed so that it operates mainly on voltage...

    Bypass & pass thru diodes

    Thanks. Yes, please refer to my illustration. Can bypass diodes not be installed outside solar panels? Your picture clearly shows bypass diodes outside the panels meant to shun an entire panel in case of shading.

    Bypass & pass thru diodes

    Hello there. You seem to have knowledge about exactly what I am inquiring about. Please see my concern on this thread that I started. Kindly give your opinions. https://diysolarforum.com/threads/placement-of-bypass-diodes.23064/#post-274967

    Reverse Bias due to shading and Bypass Diodes

    Interesting information here in this thread. I have a relating issue that seems to be unresolved, or I understood it differently. Could anyone please take a look at my query regarding bypass diodes? I want to bypass an entire solar panel from a string of solar panels attached in series. I shared...

    Placement of bypass diodes

    What I have observed is that the whole system would shut down, if one panel in a string of panels connected in series gets shaded. For this reason, there are micro-inverters instead of just one inverter. I prefer parallel configuration, but the inverter I have is designed for panels in series...

    Placement of bypass diodes

    Thanks for your message. I understand the function of bypass diodes inside the panel but I am referring to the picture you earlier posted : are the boxed illustrations strings inside one panel or they are 4 separate solar panels (or PV modules however you may wish to call them)? If they are...

    Placement of bypass diodes

    Thanks. What I heard was that bypass diodes can be placed outside the solar panel as mopet demonstrated in the picture. I am not sure if the picture refers to multiple panels or strings of cells in one panel (or PV module). What is still not clear is how to mitigate the entire power loss in a...
