How much off-grid power do you actually need?

Not every setup has the same energy demands, which is why our 48V off-grid power kits come in three options: Mid, Large and XL.

Whether you're starting with a smaller off-grid setup, need more capacity for higher daily energy use, or are planning a high-demand system, there's an option to suit different power requirements.

Swipe through for a quick look at the three kits and where each one fits.

Explore our 48V off-grid power kits on the Muller Energy website, or contact our team if you're unsure which setup is right for you.

Heading away for the long weekend?

A little preparation before you leave can make your time away much easier.

Before hitting the road, take a few minutes to check your battery is charged, your solar setup is ready to go, and you've packed the cables, chargers and 12V gear you'll need while you're away.

A few simple checks at home means more time enjoying the trip once you get there.

What's one thing that's always on your pre-trip checklist?

Which 48V Power Kit fits your setup?

Off-grid power needs aren't one-size-fits-all. That's why our 48V Power Kit range gives you three options depending on the size of your setup and your energy requirements.

From the Mid Kit for everyday off-grid energy needs, through to the Large and XL Kits for higher-demand systems, you can choose the level of battery storage and power that suits your setup.

Swipe through to compare Mid, Large and XL and see how the range scales with your energy needs.

Not every design makes it to market, and sometimes that’s part of good engineering.

We recently pulled an interesting project from the Muller Energy R&D vault: a constant-current active balancer prototype designed to maintain its full balancing current right through to the end of the balance cycle.

The concept worked on paper and on the bench. But as we worked through the real-world edge cases, the added circuit complexity, cost and size raised an important question: was it actually solving a problem that needed solving?

In our latest blog, we take a look at the idea, how it worked, the challenges we encountered and why we ultimately decided not to take it to production.

If you enjoy the technical side of LiFePO4 battery systems, this one’s for you.
