I know that batteries should be connected before MPPT and when dissconecting the MPPT sould be first so what happens if the battery fuse blows while panels are still producing power , will the MPPT be damaged .

Thank you i really o appreciate you taking the time to read and more importantly pass on your observations/thoughts which i have taken note off . In general i now feel more confident about making the final conections , the continuity i was seing in so many places was a concern and although i...

Would someone knowledgable please look at the circuit and tell me if its safe or has flaws or needs moifying before i turn on and possibly find out the hard way . The Lithium battery is sufficient to cover our normal consumption between the hours of 6pm and 10am , when we have bad weather and...

I am building a mobile tubular steel rack for my Solar Equipment and Batteries , the back panel is now a 2mm sheet of steel and the MPPT , Inverter/Charger , and DC to DC Charger are mounted on it with Positive and Negative BusBars mounted on an insulated board lower down Behind where the...

Friend who know nothing about Solar need to replace his 12 x 2 Volt 600 Ah lead Acid batteries , he needs either 2 x 12 volt 400Ah or 2 x 24 volt 200 Ah , cost , space and weight are not factors tha need to be concidered so which is the better option .

While i admit im used to Lead batteries and know very little about LifePO4 but Im concerned the aboiut the charging and behavior of my recent first purchase of a 100 amp/Hr 24 volt one . The battery charges normaly for a few hours getting to around 90% then all of a sudden within a couple of...

Would appreciate any suggestions or input on a situation my friends are suddenly encountering . Their Flooded batteries are around 7 years old and looking back via Victron Connect I can see they would normally spend several hours in Bulk then a few in Absorption but was rare for them to go into...

Thank you Sunshine for your explination , I hadnt reconised there was no current going in while there was voltage , makes sense to me now .

Now sure what to expect from my new LifePO4 battery , it came with 40% charge and a voltage of 26.2 as the manual says it would and i left it standing for 2 months before charging . When charging i noticed the Victron DC to DC charger was going through Bulk chargewith voltage slowly rising as...

Is it safe to use much smaller cables between different pieces of equipment when they are close together . The manual says that from my batteries to my Victron 24 volt 1200 watt inverter requires 25mm cables between 1.5 and 5 mtrs ,mine is 1 mtr apart but i am wondering if i have to use the...

Is there such a thing as a Manual DC change over switch made to mount on a DIN rail inside a consumer box next to the Isolation switches and surge protectors , i dont want to install a stand alone one . Looked on Amazon and cant see anything but possible i don't know what they would be called .

My intention was to use a switch that would make conecting them both at the same time imporible , the the one you showed is ideal , 1 , 2 or OFF . My diagram was simplistic to ilistrate my concer which you both clarified and put my mind at rest on , which was using a common Negative which i feel...

I dont know low cut off because i never go below 50% they were extreemly expesive batteries , hard to know because the Fridge and the freezer cuts in and voltage drops below 23 for fraction of a secod , not long enough to see on a graph often but the lowest voltage is always recorded as around...

Thank you 12Volt , you clearly understood the question and your answer was exactly what i was hopeing to hear . My normal battery bank is more than sufficient for about 320 to 330 days a year but when the weather is bad its always the nigtimes that are a problem . At these times i have to start...

I would be very grateful if someone could advise me if the Backup setup illustrated here would be feasible and safe . For reasons i dont want to go into its not practical to incorporate a switch to isolate the Negative wire to the Busbar as well as the Positive so im concerned if there might be...
