Hi, I have a Victron Smartsolar 150/35 and I have two 485w solar panels wired in series. I'm considering upgrading my solar system with one extra solar panel that fit's the amperage of the other panels and I want to wire it in series with the residual two panels. The VOC would be 129v. It seems...

Hi, I'm upgrading my solar system after about 8 months since I built it with one extra lithium battery that I will wire in parallel with the older one. The battery is Elkersolutions lifepo4 24v 100Ah. Currently I have one 300A MRBF fuse right on the positive terminal and I'm using a 2/0 AWG...

Hi, I'm upgrading my solar system after about 8 months since I built it with one extra lithium battery that I will wire in parallel with the older one. The battery is Elkersolutions lifepo4 24v 100Ah. Currently I have one 300A MRBF fuse right on the positive terminal. What I researched so far...

No, I don't have that kind of a charger. Wouldn't it be more appropriate to contact the seller before doing anything? It seems like a warranty issue. I tried that multimeter on my car battery and it shows correct measurements so it's definitely something wrong with that Elkersolutions battery.

Hi, I just finally connected together my solar system and the Smartsolar does not turn on after connected to a battery. I suppose it should turn on the small light, but it doesn't. I checked the voltage of the battery (24 volt battery) and it shows only around 2 volts. When connected with the...

I want to thank you for taking the time to explain this to me. Finally I think I understand what I was missing. So it doesn't matter if you're using a busbar or not. Everything is interconnected, creating a system and the SCC is the only device that can put the system voltage back to it's 100%...

No it's the combined length. Both positive and negative cables. When you click next to the red asterisk it shows info about each input. I attached a screenshot.

I use this calculator - https://www.explorist.life/wire-sizing-calculator/ . When you put 300A, 24v and 2ft length, it says 2/0 AWG. I never plan to go above 300A and my main fuse is at 300A as well. So why do they say in the description that 2/0 is only good for 200A max. Based on the wire...

Hello again,? I ordered this product https://www.bluesea.com/products/7748/SafetyHub_150_Fuse_Block and I'm just trying to figure out what size cable should I use between this Safetyhub and my 24v battery. As you can see in the description, it says for maximum combined operating amperage 200A...

Okay, you convinced me. I ordered this https://www.amazon.com/Low-voltage-Miniature-Circuit-Breaker-Panels/dp/B0746DLP7S/ref=mp_s_a_1_3?crid=2N4Y64P4BEVNC&keywords=dc+double+pole+circuit+breaker&qid=1675080658&sprefix=dc+breaker+double%2Caps%2C225&sr=8-3 and this...

Hi, I'm just ordering the last few things I need to finish my project and I was wondering if there is any other reason to install a solar disconnect except for the practicality of it? I'm hesitant to spend any extra money because I already spent more then I planned. Is there any actual...

I'm thinking of going for the MRBF fuse. I found this one with the holder on amazon https://www.amazon.com/Bay-Marine-Single-Terminal-included/dp/B07LC6B7DR?th=1 . I probably need 300 A because I'm going to connect it to a busbar. Do you know of some shop that has MRBF fuses or busbars and...

Thanks for the explanation. It really helped. So the system is configurated in a way that the power stored in the battery is only used when the SCC can't provide enough from the solar panels. Is this correct? But which device manages this? Let's say you start the coffee maker, so the inverter...

So you're saying the MRBF fuse has sufficient AIC rating for my 24v lithium battery? Also I have a somewhat dumb questions about basic laws of electricity. These questions were the reason I didn't want to get into busbars at first. If we look at the busbars on the diagram you sent, we can say...

Thanks for the calculation. I'm planning to build my system like on the diagram I attached. No bus bars. Does it mean I need to use three T-class fuses if I have 3 pairs of cables connected to the battery terminals? I have a 24v 100ah lithium battery
