What Size Solar Battery Do You Need?

In this video, Andy shows us how to size a home battery solution using the solar calculator from SolarReviews. There is no one-size-fits-all answer - finding the right solar battery. Calculating solar battery size depends on what you want out of the battery. Some homeowners want home battery backup in case the power goes out. Sizing a battery backup system will depend on what appliances you want to run and for how long. Others calculate battery size based on how much energy they use when power is most expensive. Then, they can charge the battery when electricity is cheap and drain it when rates are high to reduce their energy bills. The most economical option for home battery storage is finding the right battery size for your solar system. You can size your battery bank based on how much excess solar energy your solar panels will produce during the day. This way, you aren't buying solar batteries that your panels will never be able to charge. The SolarReviews home solar battery calculator lets you choose how you would like to use a battery, so you can easily find what size battery bank will meet your needs.

I live in Cape Town, South Africa. I am a pensioner so have very little spare cash. I built a 24v 50ah battery with BMS with 4 * 100w solar panels connected in series with Victron solar charger and a 3000w chinese inverter. This gets my 2 small fridges and freezer running while the sun shines. We have power outages all the time called "load shedding" between 2 and 4 hours at a time. I am going to upgrade the battery to 24v 200ah when I have saved the money, probaly in 4 months time, then save for a 48v system.

Don't bother watching. The website doesn't work anymore. Just sits there "retrieving results".

I was really looking forward to a suggestion on helping me determine what size solar battery I need for my home. Directing me to a local solar installer and letting me know there is a calculator being developed is not very helpful to me.

Great viewing.I just got my hybrid solar system installed, and its awesome, monitoring the portal all the time on my phone and knowing polluting, unsightly power grids are no longer going to be my prime reliance on energy is about as satisfying as it gets.

Hey fellow outdoor enthusiasts and RV lovers! I recently came across the Segway Portable PowerStation Cube Series and it seems like a great backup power solution for our outdoor adventures. With its massive capacity, powerful output, and fast recharging capabilities, it can keep our devices and appliances running for extended periods. Plus, its waterproof technology and comprehensive protections make it perfect for any adventure, rain or shine. Definitely worth considering!

I’ve got 2 48v battery banks, 1 - 280Ah & 1 - 40Ah & I started building 1 - 320Ah my BMS ‘s are DAILY 15S 120A

Corded power tools only list one number in AMP's, is it usually the starting or running AMPS???

[bauminwi]

The calculator never finished retrieving results. It’s broken.

What if I already have solar panels and I want to add batteries. How do I determine how many batteries to get?

[things_that_click]

Tried the tool and the progress bar just sits once compleated. Also it seems to be doing a LOT of work just for me adding a zip code....seems sketchy.

For me the more power the better cause each day is different
Might use more power might not.


I want off grid power

Think there was a different reason for systems without a battery. A there weren't any and B if there was a battery available the ROI was 40 years iow too expensive. They have become a little cheaper but not at a pricepoint where they should be.

[ianmburke]

Solar calculator stops at 'Retrieving results' and takes forever to get even that far...😢

[MyWasteOfTime]

Simple, if you want to save money running off batteries, reduce your usage so you need fewer batteries!

[w.harrison]

What does the size of battery you need have to do with solar power? The battery size should be obvious from your power needs in the home.

[bonniehanh-nhinguyen]

How do you calculate 18kw solar needs 45kWh?

WHY ARE YOU BOUNCING?? I can't watch you. I had to shut off my monitor and just listen! Sorry, I do appreciate your content. Just can't watch it.
