Is Tesla Powerwall 3 worth it?
If you want one well-supported box that runs your solar and battery together with strong whole-home backup, it's one of the easiest choices. If you want to scale capacity in smaller steps or pay less per kWh, look at SigEnergy or Sungrow.
Good fit if…
- ✓You want whole-home backup from one unit
- ✓You're adding solar at the same time (the inverter is built in)
- ✓You drive a Tesla or want Tesla home charging from the same installer
Look at another battery if…
- ✓You want more than 13.5 kWh but in smaller steps
- ✓You're adding a battery to a newer inverter you want to keep

What our customers say.
“My power bills are virtually non existent now”
Amazing service!!! Michael and his team showed up on time and delivered everything they promised. They cleaned up after themselves and all the team were so polite. Getting solar and batteries was a bit of a struggle to navigate, however once i spoke with michael I had peace of mind. We did have an issue with the app connecting which micheal sorted out straight away. Highly recommended. Thanks you so much. My power bills are virtually non existent now🙌
“The best decision we could have made”
Choosing MF Energy for our solar transition was the best decision we could have made. From the initial consultation to the final walkthrough, the entire process was seamless, transparent, and completely stress-free. The highlight of the experience was definitely the installation team. They were professional, efficient, and incredibly respectful of our property from start to finish, completing a flawless job ahead of schedule. Highly recommended! Thank you Micheal and team!
“Michael and his team don’t muck around”
MF Energy did a fantastic job installing my 15kw solar and 40kw battery + EV charger. It was a complex installation and they did it efficiently and professionally. If you’re reading this, save yourself time and effort - just go to them directly if you want the best quality at the most competitive pricing. Michael and his team don’t muck around.

Can Powerwall 3 work with my existing solar?

Often, yes. Powerwall 3 has its own solar inverter, and Tesla also supports connecting it alongside existing systems. We check your setup and recommend the simplest option.
