The short answer
All-in-one power stations fail as a unit and cannot be diagnosed in the field — when the inverter section dies you lose the battery too, because they live in the same sealed box. Timber systems use discrete, individually replaceable components: LiFePO4 storage, a separate inverter, a separate charge controller, 200W solar, alternator charging, and shore power. You replace one part, not a system.
Every few months someone asks why we do not just drop a big all-in-one power station into our builds and call it done. It is a fair question. Those units are genuinely impressive: battery, inverter, charge controller, and display in one sealed box, one plug, done.
Our concern is not brand loyalty. It is what happens in year four, five hundred miles from a town.
Integration is great until it is not
When your battery, inverter, MPPT controller, and charging electronics live inside one sealed enclosure, they succeed together and they fail together. If the inverter section dies, you do not replace an inverter — you ship the whole unit somewhere and wait. Meanwhile you have no power at all, because the battery was in there too.
A modular system fails gracefully:
- Inverter goes down? You still have 12V lights, water pump, fan, and fridge.
- Charge controller goes down? Alternator charging still works.
- One battery goes down? The rest of the bank carries the load.
You limp to a town instead of stopping in one.
Diagnosis is the real cost
This is the part people do not think about until they are living it. A sealed all-in-one tells you what it wants to tell you — an error code and a support phone number. There is no meaningful way to put a meter on anything, because there are no accessible terminals between subsystems.
With discrete components, troubleshooting is a process anyone can follow. Check the battery voltage. Check the input at the inverter. Check the output. You find the problem in ten minutes and replace one part for a fraction of the cost.
We can walk a customer through that on the phone. We do, regularly.
Serviceability is a design decision
Timber systems use discrete, individually replaceable components: LiFePO4 battery storage, a separate inverter, a separate charge controller, 200W solar, alternator charging, and shore power. Every piece is a standard part with a standard form factor.
In eight years, you replace one component, not a system. That is the difference between a repair and a write-off.
What you actually get
Standard on every Camp and Rambler:
- 200W roof solar
- Alternator (DC-DC) charging
- Shore-power charging
- 120V outlets, USB ports, and a 12V outlet
- Dimmable LED lighting
A battery expansion pack is available for $1,795 if you run a bigger draw.
Build it so it can be fixed, by you, on the road.
When an all-in-one is the right call
To be fair to them: for a weekend DIY build where the alternative is no electrical system at all, a portable power station is an excellent answer. It needs no electrical bay, no bus bars, and no wiring diagram, and you can carry it to a picnic table. That is genuinely the right tool for a lot of people, and it is what our kit electrical package is designed around.
The trade-off only bites when the van becomes the thing you depend on. Sizing guidance is in how much power does your camper van really need.
Frequently asked questions
Are all-in-one power stations good for camper vans?
They are excellent for weekend builds where the alternative is no electrical system at all — no electrical bay or wiring diagram required. The drawback is that the battery, inverter, and charge controller share one sealed enclosure, so a failure in any one of them takes the whole system offline.
What happens if a component in my van electrical system fails?
In a modular system you replace that component. Because Timber uses discrete parts with standard form factors, a failed inverter still leaves you 12V lights, fan, water pump, and fridge, and a failed charge controller still leaves alternator charging.
Is the Timber electrical system expandable?
Yes. A battery expansion pack is available for $1,795 for builds with a larger daily draw.
What comes standard in a Timber conversion electrical system?
200W roof solar, alternator charging, shore-power charging, 120V outlets, USB ports, a 12V outlet, and dimmable LED lighting — standard on every Camp and Rambler.
