How Much Battery Storage Should I Get With My Solar System? Lets Discuss It!
Publicado 2024-06-14
How much solar battery capacity to get, is a dilemma that every customer struggles with as they embark on their solar journey. It is not such a straightforward black-and-white answer either due to the various ways you can make battery storage work for you!
In this video, I try and discuss the main 3 considerations to make to help you determine the level of battery capacity to go for in the beginning whilst also thinking about the future!

How much battery storage to get is a difficult decision to make but hopefully, this video helps a little to make the right choice from the outset!!! Let me know in the comments how much battery storage you think is the right amount and if you plan to force charge and force discharge your batteries?! Thanks for watching! :)

One thing to watch out for is the battery cell configuration. I'm having a bit of a todo with my solar installer because the batteries i got are a weird 15 cell configuration whereas a normal LiFePO4 48v battery has 16. This means that i can't add any other type of battery than the one i got, whereas i want to be able to grab any standard battery out a DIY one like the seplos mason kits and connect it to the battery bus. I accept this isn't a use case for most solar customers but it is for me.

Great video, really clear and practical

The ability to mix battery sizes such as sigenergy is useful .

HI - Just had a system installed - 5.92 Kwh / 6kwh Inverter / 5.8Kwh Storage which I want to increase does the fox app automatically update if you add a battery or do you need administartion access. System is Fox ESS

if i went on to their export tariff would i be abled to still keep my olf government FIT payments ?

All well and good until you discuss costs. A 10kwh batterry if used to its full over its lifetime is going to cost about 10ppkwh. Add that to your 7.5p import charge and then add conversion losses and you are already losing money exporting to the grid from the battery. If space allows, you would be better off maximising your PV arrays and selling surplus PV at 15p and buying in what you need on a tracker tarrif at about 20ppkwh. And, if you dont fully discharge your battery every day, and fully charge it everyday, your efficiency goes down, and your 10ppkwh quickly becomes 15ppkwh. Batteries come into their own if you have power outages and have ahome back up system, but I doubt you will barely break even just buying and selling ! It would be nice to see you doing a sales arguement for a 10kwh battery on numbers alone

You said it was a 10 minute job for you so what is the cost you charge Bfor a 10 minute installation?

I thought I needed around 10 kw . Now I have 45 kw and it's perfect but it just goes to show..... You will need more than you think. And the more batteries you have the longer they will last because they are not being worked as hard
