            Is there a difference aside from jacket color (resistance, performance, ect) in regular #8 stranded cable and ground stranded #8 cable? Can I use #8 b stranded cable as ground cable and tape the ends green?

              So before I make the purchase need to make sure this fuse/breaker fits into system which is 3 260w panels in series (going to 6 in couple months) 50A 150v MPPT/ (8) 6V 230a/h battery bank wired in series 48v/ 2000w 48v AIMS inverter. Cable runs from panel to mppt are 50' using (#8 cable) All the other runs will be no more than 5' using cables per calculator suggestion.

              Going with:
              Blue Sea System285-Series 40A Circuit Breaker (between solar panels and MPPT)
              Blue Sea System285-Series 60A Circuit Breaker (between MPPT 50A and Battery Bank)
              Blue Sea System285-Series 80A Circuit Breaker (between Battery Bank 48v 230a/h to Inverter 48V 2000w cont)
              Blue Sea System 300A m-Series Battery Switch
              Looking to have a fuse directly on the positive lead from the battery. Any suggestion? Looking at Blue Sea System MRBF Terminal Fuse Block with 250A fuse

              System will be ungrounded for a few months until I recover financially from the initial investment then will ground completely with a Lighting arrestor integrated

                Interesting thread--hope people are recovering well on your island.

                I have a 428AH leaded flood acid battery bank with my system and mounted this T-type fuse in AWG 00 battery cable that runs from the bank to the inverter: It seems like a very simple and solid product. Not sure how the price compares to the Blue Sea one you're considering, it runs about $50 shipped.

                Although close to the postive post of the battery is good, you don't necessarily want this in your battery enclosure because it could produce a spark which could potentially ignite any accumulated hydrogen gas venting from the batteries. Mine is mounted on the outside of my battery box--24" of cable length away from the post.

                  Good day I want to find out if I can connect a 6A10 and a 10A10 diode on a 100W 12V solar panel, we have two 12 volt batteries with a 1200W inverter and a 12/24V charge controller. Is it compulsory for both diodes to be the exact same size or doesnt it matter?

                    3 steps here
                    1) get a baseball bat (wood , not metal)
                    2) find the source of the information about using a diode, use the bat and smash the source. Diodes have not been needed with panels for 20 years, unless it's a
                    DIY panel that has no factory diodes
                    3) forget about diodes and re-ask the question

                      Question...
                      Do I need to vent the batteries enclosure I used? Room its located in is well vented? Attached a picture of enclosure I used
                      Attached Files

                        are those batteries in the house? if so you need a sealed battery box that is vented to outside.

                          They are inside house on a room with multiple windows and room is almost never used exept for storing miscellaneous stuff.

                            So what ? Think safety first. See Butch's last post to this thread.

                              well that doesn't really matter. If they are inside the house then they need to be inside a SEALED container that is vented to outside. That plastic container does NOT look sealed.
                              The opening for the wires must be below the top of the batteries but above the bottom of the box (prevent acid from leaking out and prevent hydrogen from leaking out.

                              When you charge batteries they can produce Hydrogen and Oxygen a very deadly explosive combination, in addition to acid mist which is highly corrosive.
                              You do not want any electronics in the box as the acid mist will corrode it and any possible arc could cause an explosion.

                              The best venting is a gravity vent (think of an upside down drain system) as hydrogen rises. You want this to be thermally neutral so that you do not create a thermal vent cooling the batteries and room. The easiest way to do this is to use a large plastic pipe that terminates inside the sealed box at the top, with a smaller metal pipe that runs inside the larger plastic pipe and terminates an inch or so from the bottom of the box.
