    Minimum battery capacity for Victron Multiplus II 12/3000

    Cheers for your opinion but thanks to the help I received from members of this forum, everything is up and running and working perfectly for my needs.

    Minimum battery capacity for Victron Multiplus II 12/3000

    I think Joey was pretty plain about it ? but yes, after looking the prices do seem very very high. 48v; perhaps, I just wonder if this will be in excess of my needs at the moment... If we do go for a whole house system at a later date it will be for a different house and that will definitely...

    Minimum battery capacity for Victron Multiplus II 12/3000

    Hi, No, not yet; I've got the panels, charge controller, distributor, cerbo GX and lynx shunt; just the inverter and batteries to buy. I've actually been debating about whether to go with a 24v system as it looks like it might be a better fit, so I will definitely check out the standard...

    Minimum battery capacity for Victron Multiplus II 12/3000

    ? Fair point on the batteries. Thanks for the calculations; that's really useful. Going to keep thinking about this before spending unnecessary money; feeling a bit skint as it is after buying the other bits!

    Minimum battery capacity for Victron Multiplus II 12/3000

    Thanks, Just so I'm clear, can you clarify what you mean by limited use install and driving the victron at a limited level? How is using a smaller battery bank detrimental if the load being used is well under the spec of the units and batteries capacities? Or do you mean that it's best to...

    Minimum battery capacity for Victron Multiplus II 12/3000

    Hi All, After looking through the literature for the 12v Victron Multiplus II 3000VA, it states a minimum requirement of 400Ah battery capacity. This system is a bit overkill for my present needs (small shed/cabin home office) but I purchased it to allow for future additions/upgrades. The max...

    Got it. Cheers again for the info; this has really helped my understanding of things.

    Lynx Shunt Wiring

    OK, great I'd thought it would be around 500a for the lynx shunt (ie. 150a x3 plus a bit extra). If I went with a modified lynx power in for the battery connections, would it still be best to place the fuses on the battery positive terminals or would putting the fuses in the modified lynx power...

    Lynx Shunt Wiring

    OK, that's great. Just so I'm clear; rather than connecting the batteries in the conventional parallel way, each of the 3 batteries will feed into the lynx power in as 3 pairs of cables. I then put a fuse with one of the holders you've specified directly on the positive terminal of each...

    Lynx Shunt Wiring

    Hi Joey, It's a 12v system as per the one Will demos. I'm still deciding at the moment but was going to go with 3x100ah lifepo4; possibly TN Power or if my budget can stretch, the Victron superpacks. Just so I'm clear, are you saying that connecting the batteries to a lynx power in, then to...

    Lynx Shunt Wiring

    Having recently watched Wills excellent youtube video called Victron systems made easy, I loved the neatness of the system and have taken the plunge and slowly been purchasing the components that he demos for this 12v setup. With the help of this forum I’ve wrapped my head around the solar...

    The perfect analogy; thanks Tim that's really clarified things in my mind. Thanks for helping me.

    Max Overpanelling for Victron MPPT 100/50

    Perfect thanks Tim, that makes total sense; just so I'm 100% sure I won't cause any damage by adding as many panels as I wish, as long as I don't exceed the input voltage?

    Max Overpanelling for Victron MPPT 100/50

    Thanks Tim, but is that to say that I could theoretically use a 3S4P configuration (not that I would as I'm not that wasteful) and it wouldn't cause damage to the controller having 2400W of power being routed to it? Does the excess power just stay in the panels somehow?

    Max Overpanelling for Victron MPPT 100/50

    Thanks all, Littleharbour; I corrected the post to show that it is a 12V system. Tim; as you suggest I was thinking of a 3s2p configuration as that would keep me comfortably under on volts and well under on amps. Phil; I'm currently checking panel positions in various spots of the garden to...

    Max Overpanelling for Victron MPPT 100/50

    Hi All, Quick noob question: I'm still putting together a 12v system and have a Victron Smartsolar MPPT 100/50 and 3x Renogy 200W panels which each have a Voc of 27v and an Isc of 9.66A. My intention was to wire the 3 panels in series (combined Voc of 81v) as this would be comfortably under...

    Victron MPPT confusion

    Thanks for this; I'll check out the link. I'd rather err on the side of caution than risk damaging anything so it's good to know that 50A is generous.

    Victron MPPT confusion

    Thanks, that's good to know; I'm definitely comfortably under on voltage with the 3 panels so it sounds like it should be fine.

    Victron MPPT confusion

    Thanks Phil, It's a 12V system so I'm assuming the calculation of 600W/13.8V = 43.5A is based on the output of the controller to a fully charged battery? I'm still in the process of choosing batteries so need to research this more.... This being the case I take it that it wouldn't ever be...

    Victron MPPT confusion

    Hi All, I'm putting together my first proper system using Victron components and purchased the 100/50 MPPT smart charge controller to use with 3x200W panels wired in series. Following the purchase a couple of sources have made me question my choice so I wonder if you can give some clarification...

    Jackery 500 Anderson panel connector

    Hi, As the panel you're looking at has a VOC of 38.80, I would NOT use it; it could result damage to the unit due to the voltage exceeding the max input of 30V . Also, I would bear in mind that the VOC is (If I remember correctly) calculated at 25 degrees C, so if it's any colder the voltage...

    Fixings for mounting rails/brackets to shingle roof in UK

    Hi all, Does anyone know of a UK based company that provide fixings for mounting panels to shingle a roof, or can you recommend a method of sealing you have used yourself that has successfully prevented any water ingress? I've seen a few different kinds of solutions from the US such as a...

    Jackery 500 Anderson panel connector

    No worries; I've got a couple of the Jackery units myself and had been looking at the largest panels that would work with them as I'm UK based and was getting poor performance out of the Solarsaga 100W in cloudy conditions. From what I've read, the 8mm input can take up to 30V and will...

    Jackery 500 Anderson panel connector

    Should start by saying that I'm a noob but I don't see any reason why this wouldn't work; the panels VOC is comfortably under the 30v max input of the Jackery and the lead you've linked linked to says it uses 14AWG cable which I think is better than some of the thinner, cheaper cables I've seen...

    Thanks for the tips Filterguy and Svetz. In response to MisterSandals, Hedges is right; I edited my first post after a day or two upon seeing other new posts receiving replies and watching mine drop down the list; there was definitely no time limit within which to edit my post. I'll repost...

    Yes, I definitely think that with the forum being international, new posts could fall down the list and get lost quite quickly. I am in the UK, so aside from my initial post being a bit long winded, the timing wouldn't have helped in my getting a reply....

    What a friendly bunch! Thanks for your kind replies ? Whilst I was half joking, I do see that there are several questions in the beginners forum (including my own boring tome before I edited it) that receive quite a few views but no replies. I appreciate that different forums have different...
