fhranchez: Failing battery will reduced overall AH charged to thr battery as the battery falsely get full very soon but not the instantaneous current. Reduction in current is due to dust. Wash the panel. 2 Likes |

Are u using a lead acid battery. If yes.. Do u av a shunt battery monitor installed in ur system or any type of monitor that shows the amount of amps coming n going out of ur battery? Wat side is ur panel facing. (N, E, S or W) fhranchez: |

They can both be true. Dust and dirt can lower your PV production significantly. A weak or failing battery can also limit your PV production. You should clean the panels as a first step - this is low hanging fruit. To test if your battery is a culprit, on a clear skies sunny day, disable mains/Gen input, put on a large load while the battery is in absorb or float and see if the PV watts ramp up in response to the load coming on. You could also deep discharge the battery the day before and disable solar charging until 11am - you start up the solar charging while the battery is low and see how the PV responds to a hungry battery under optimal solar weather. You need to pick an ideal solar day to run these tests and also have a backup in case solar will not be sufficient to refill your battery for that day. fhranchez: 1 Like |

Jefferyzz:ques 1: yes, lead acid(gel) Ques 2: shunt, the pwm controller has a amp monitor Ques 3: north or south, I'm not sure |

Not like that. U need a standalone monitor like the 1 below fhranchez:

Who knows if this diodes can function like fuse. They are way cheaper than fuse n fuse holders. More than 2x cheaper sef

Re: Solar Energy, A Complement To FTA by ojeysky(m): 11:37am On Dec 04, 2022 |
Jefferyzz: I believe it acts as fuse only drawback is that you can get it in higher amps ranges so if your string current is not high then you are good to go |

Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 1:28pm On Dec 04, 2022 |
No diodes are not fuses - diodes allow current to flow in only one direction. If I recall correctly a diode burns out if higher than rated amps pass through it - the burnout is in such a manner as may cause a fire or other damage. Fuses are designed to fail safely when the circuit they protect is overloaded. Decent panels usually have diodes built in same as the charge controllers - I am wondering what OP is trying to achieve substituting a diode for a fuse - if the goal is to protect your panels from perhaps some short or other failure then use a combiner box with breakers per string of panels or if you really want to use fuses then take the time and trouble to do it right. ojeysky: 1 Like |

ojesymsym:You may see it but I doubt the effectiveness of it. Someone talked about putting some super capacitors in parallel with his battery, right at the inverter terminals. That would give a big current boost when a high demand load start. I think you need an inverter/battery capable of handling the start up surge. The goal should be to avoid using battery to power freezer, rather using surplus pv while battery is fully charged during the day. |

NiyiOmoIyunade: Those stuff are actually called fuses(you may Google it) but they act as you've described. Usage scenario is when you don't want current from PV to go above certain level. I was considering this for my home setup at a time but I figured that Deye does cap the current without negative impact. Not all CC does that apparently. |

Re: Solar Energy, A Complement To FTA by Jefferyzz(m): 5:56pm On Dec 04, 2022 |
The purpose is to blowout Incase there's a short higher than 15a. D diode is built inside an mc4 connector. I think that can handle the fireworks. Yh. Current from d panel is meant to flow in 1 direction. Backflow will damage d panel if higher than d figure of max series fuse. N a pair is lesser than price of 1 fuse with d holder. NiyiOmoIyunade: |

NiyiOmoIyunade: You'll be surprised at the stunt some tech people pull off at jobs. I've seen someone bill for 4mm² 3 core flex, one for input and one for output. The tech guy ended up using one of the wires (3 core) for both input and output. How he achieved this is both criminal and at the same time genius. The 3 core wire was used this way, L was used for input live, the neutral wire was used for both input and output neutral (inverters share a common neutral for both input and output) and the third wire, earth, was used for output live. Dude did not really care for earth, "after all it works" So he bought only 30m of cable and pocketed the money for the other 30m meant for output wire. |

jonescosmo: Am looking at those battery cables, they don't seem to be above 16mm? I will suggest you do 35mm or at least 25mm considering the load as I assume you will be doing up 10kw average? I can even see from the image that you are already discharging at above 11kw 1 Like |

ojeysky: They are actually 35mm x 2 on each pole. I used single 35mm initially but they were heating up while charging at 240A. So instead of linking the 2 batteries, I let each battery travel to the inverter on its own. Now the heating is gone. I have the breakers to worry about now. It's rated 125A and I'm pumping 240A through it. Instead of it to trip, it's just there heating up. |
