    I dont know where to find the 12amp inline fuse. 10awg cable. Mc4 connections. Is this suitable? https://www.solarpanelstore.com/collections/breakers-fuses-dc/products/midnite-solar-din-mount-breaker-mnepv-1-63a-choose-ampere-rating-mnepvx?variant=22111881330777 or do you know a good source to...

    I just have one inverter hooked up right now. 24v 2000watt samlex pure sine wave. I have a 1000watt inverter not being used right now so i could incorporate that if neccessary. My main goal was operating a freezer and then the fridge was my next priority. I know its just a small operation so...

    Ok, Im not stuck on the dryer. I can hang dry. What about everything else? It is off grid. I want to wire 2 20amp outlets in kitchen (freezer/fridge). I want to wire 3 20amp outlets downstairs (washer, dryer, dishwasher) All appliances I mention are portable and energy efficient ones. They are...

    heres the technical data from the panel: what size fuse would apply for this please?
  • Post in thread: 1000watt panel system with 10 100watt panels

    so do i just disregard the solar panel instructions which say they recommend no more than 4 in parallel? Just do 2 5 strings, 5 and 5 paralelled and then seriesed for 24v 500watt system. My batteries would become 24v 200Ah. They are lithium batteries. Does this sound reasonable to power a...

    Does this drawing make sense? The panels are 3ft by 2ft-3in. The deck is south facing. 5ft wide by 4.5ft high usable sun space uninterfered with by eaves. Ive drawn a right triangle with 5ft and 4.5ft. Multiply those then divide by two for 11.25ft hypotenuse on which the panels can be...

    Hello. I am in a little dilemma with setting up my solar. I initially bought 10 100w panels which i found out is a newbie mistake. https://www.amazon.com/gp/product/B08721CBST/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 Woops. I set up a return for them with amazon because it was free...

  • Post in thread: Parallel cord length question

    Hello! I am paralleling my LiFeB04 batteries for 24 hours before their final configuration. I am using 2/0 awg cable. For the parallel, do the cables need to be same length from one battery to the next. If one is triple in length to the rest of the cables but the others are all similar in size...
  • Post in thread: Solar upgrade question, I am new to this

    I have 200 watts, 1000 inverter, 2 100ah batteries, pwm charge controller all 12v. I am looking to upgrade the system. I am not good with numbers, math, engineering and am seeking help. All I power right now is lights. This is off grid. I want to be able to power a fridge/freezer, lights...

    I think.I understand what you mean. Im waiting for the fuse to arrive so I can work it out. My batteries had stated they need to be charged fully individually and then placed in parallel 24 hours, then configured as needed. I have a lithium battery charger but would have to use my generator...
  • Post in thread: 1000watt panel system with 10 100watt panels

    i attached a photo of the instruction page cropped down to reduce size , so i am considering buying one more 2 pack and doing 3 strings of 4 each for 1200w at 48v. Is this a good move? My batteries will be 48v 100Ah now and im not sure if that makes sense or would be a good move , really need to...
  • Post in thread: How to disconnect batteries safely

    I have 4 12v 100ah LiFeBo4 batteries( Amperetime brand ) hooked up 2s2p. They were running great until one day the solar array wasnt charging them due to a cable and the batteries ended up getting completely discharged. The problem was quickly fixed but the batteries are not operating at their...
  • Post in thread: 1000watt panel system with 10 100watt panels

    W what would 4 strings of 3 give me? would it be beneficial to bump.up the controller? i will do the 3000w.inverter/charger. Do you recommend anything? what size.wires.should i get? thank you!
  • Post in thread: System down. Please help!

    That's what the battery level reads on the charge controller.
  • Post in thread: System down. Please help!

    The batteries are Amperetime bought off Amazon.

    thanks. That is very helpful to me how you explained it. How would i know if i need the rapid shutdown? I live in the mountains at 3500ft elevation. In wintertime averages 59 daytime, 35 nightime and Im estimating. I think 20 degrees would be lowest ever and a rare extreme. Im in california, not...
  • Post in thread: 4 405w panels vs 12 100w panels...

    there is a 50a breaker for pv before the charge controller. After the charge controller i should have a 50a fuse, then another 50a breaker before connecting to the battery. Is that correct? I like the midnite solar 50a breakers you showed me. My problem is the box enclosure. I found the quad...
  • Post in thread: 4 405w panels vs 12 100w panels...

    so if the max is 12A that means i should get 10A? Or should i get 15A holder and insert 12A fuse in it? I dont see any 12A fuse holders and fuses. Only 10 or 15A holders but I can find 12A fuses. What do these fuses do? Are they absolutely neccesary for a solar setup?

    please confirm, i will need 3 pairs of y branch connectors...
  • Post in thread: 4 405w panels vs 12 100w panels...

    thanks for this info. Im understanding i need a 10a fuse per string (so 3 of those). I need a 40a fuse just before the cc. I need a 250a fuse before inverter. Please correct me if im wrong. with the y cables i would like to connect 8awg wire just after the connector. They list 10awg to 14awg...
