NIX | The Distributed Campervan Power Grid ⚡🚐🔋

A technical deep-dive into the NIX three-Jackery architecture and why it quietly turns Vanilla into a micro-grid.

There is a peculiar moment in campervan electrics when the system stops being “a battery and some lights” and becomes something much closer to a power network. Engineers call this concept a distributed energy system: multiple storage devices, multiple conversion paths, and the ability to move energy where it’s needed.

That is exactly what you’ve built.

With:

• Exide EZ850 100Ah AGM leisure battery

• Jackery Explorer 2000 v2

• Jackery Explorer 1000 v2

• Jackery Explorer 240 v2

• Victron Blue Smart 10A charger

• 300W pure sine inverter

• solar input (120W roof + SolarSaga panel)

Vanilla now operates more like a mobile micro-grid than a simple campervan.

The interesting thing here isn’t the individual devices. It’s the architecture — the way energy flows between them.

And that’s where the NIX concept gets interesting.

⚡ Core System Components

🔋 Leisure Battery – The Fixed Grid Anchor

Your installed battery is the Exide EZ850 100Ah AGM.

AGM batteries have characteristics that make them ideal for vehicle electrical systems:

Nominal capacity

100Ah × 12V ≈ 1200Wh

However usable capacity is typically 50% if you want long life.

Practical usable energy:

≈ 600Wh

Advantages:

• high current capability• stable voltage output• tolerant of vehicle vibration• inexpensive compared to lithium

Limitations:

• lower energy density• slower charging• deeper discharge reduces lifespan

The AGM battery therefore functions as the base electrical layer of the van.

🔋 Jackery Explorer Fleet

Your three Jackery units create a tiered lithium storage system.

Lithium batteries behave very differently from lead-acid batteries.

Advantages include:

• high energy density• high cycle life• stable discharge curve• high inverter efficiency

Let’s look at each unit technically.

Explorer 2000 v2 — High Capacity Node

Specifications:

• capacity: ≈ 2042Wh

• AC inverter output: 2200W

• USB-C output: 100W

• solar input: up to 400W

• weight: 17.5kg

This unit contains roughly three times the usable energy of your AGM battery.

In practical terms it can run:

• induction hobs• kettles• microwaves• power tools• heaters

It is essentially a portable power station.

Explorer 1000 v2 — Mid-Tier Energy Buffer

Specifications:

• capacity ≈ 1070Wh

• AC output 1500W

• USB-C 100W

• solar input 400W

This unit functions as a secondary storage buffer.

Ideal loads include:

• laptop charging• drone batteries• lighting systems• portable cooking

It provides a balance between power and portability.

Explorer 240 v2 — Portable Micro Power Unit

Specifications:

• capacity ≈ 256Wh

• AC output 300W

• USB-C 100W

This unit is perfect for small loads:

• phone charging• portable lighting• laptop use

Its main strength is mobility.

You can take it outside the van easily.

⚡ Total Energy in the NIX System

Let’s estimate total stored energy available.

Leisure battery usable energy:

≈ 600Wh

Jackery units combined:

2000 v2 ≈ 2042Wh1000 v2 ≈ 1070Wh240 v2 ≈ 256Wh

Total Jackery energy:

≈ 3368Wh

Combined system energy:

≈ 3968Wh

In simple terms:

Vanilla now carries roughly 4kWh of usable electrical energy.

For comparison:

A typical UK household uses 8–10kWh per day.

Your campervan therefore carries about half a house’s daily electricity consumption.

That’s impressive for a vehicle.

⚡ Power Conversion Infrastructure

To move energy between components the system relies on several converters.

300W Inverter

Function:

12V DC → 230V AC

Maximum theoretical current draw:

[I = \frac{P}{V}]

[300W ÷ 12V = 25A]

Allowing for inverter inefficiency:

≈ 30A draw

This is well within the safe range of 50A Anderson connectors.

Victron Blue Smart Charger

Output:

10A at ~14.4V

Power output:

[10A × 14.4V ≈ 144W]

This charger uses a multi-stage charging algorithm designed specifically for AGM batteries.

Charging stages:

1 Bulk2 Absorption3 Float4 Storage mode

This ensures the AGM battery receives proper voltage and current control.

⚡ Energy Flow Modes in the NIX Architecture

The clever part of your system is that energy can move in multiple directions depending on circumstances.

🚐 Mode 1 — Van Charging Jackery

Energy flow:

AGM Leisure Battery
        ↓
300W Inverter
        ↓
Jackery AC Charger
        ↓
Jackery Battery

Typical charging power:

≈ 60–100W

Current draw from AGM battery:

≈ 8–12A

This is extremely gentle for a 100Ah battery.

This mode works best while driving, when the alternator replenishes the leisure battery.

🏕️ Mode 2 — Jackery Charging Van Battery

Energy flow:

Jackery AC Output
        ↓
Victron Blue Smart Charger
        ↓
AGM Leisure Battery

Charging power:

≈ 144W

This allows the lithium battery to top up the AGM battery overnight if necessary.

🔄 Mode 3 — Independent Power Systems

Each battery can also power loads independently.

Example distribution:

Explorer 2000 → cooking appliancesExplorer 1000 → drone chargingExplorer 240 → personal electronicsAGM battery → van systems

This spreads load across multiple power sources.

⚠️ Why Continuous Power Loops Should Be Avoided

Running the full loop:

Battery → inverter → Jackery → charger → battery

creates energy losses at every stage.

Typical efficiencies:

Inverter ≈ 85–90%Jackery charging ≈ 90%Jackery inverter ≈ 90%Victron charger ≈ 90%

Combined efficiency:

[0.9 × 0.9 × 0.9 × 0.9 ≈ 0.66]

Only about 66% of energy returns to the battery.

34% becomes heat.

Physics wins again.

⚡ The Anderson Connector Concept

Using 50A Anderson connectors turns the system modular.

They act as high-power DC docking ports.

Advantages:

• robust mechanical connection• genderless connectors• high current capacity• simple plug-and-play operation

This makes it easy to connect:

• inverter

• solar charging cables

• emergency jump leads

• portable chargers

Truck mechanics have used them for decades because they simply work.

🧠 Imagined Public Reviews of the NIX System

Campervan Owner (UK Camperlife Forum)

“This is actually a really clever way of using portable power stations. Instead of replacing the leisure battery system, the Jackery units become an extension of it. It’s modular and gives you redundancy.”

Overland Vehicle Builder

“The interesting part here is the distributed battery architecture. Expedition vehicles often use multiple battery banks for exactly this reason. The NIX approach achieves a similar effect using portable power stations.”

Electrical Engineer

“From a technical standpoint the system is sound as long as conversion loops are avoided. The use of a proper smart charger like the Victron ensures the AGM battery receives correct charging profiles.”

Solar Installer

“Many camper systems fail because everything relies on a single battery bank. This setup spreads energy across several storage devices, which increases resilience.”

Outdoor Tech Reviewer

“What I like about this design is flexibility. You can run the van from the installed battery, or run appliances from the Jackery units, or recharge one from another. It’s essentially a portable grid.”

⚡ Professional Perspective

From a systems engineering standpoint the NIX architecture demonstrates three principles used in larger power networks.

1 — Distributed Storage

Multiple battery banks reduce risk and increase flexibility.

2 — Modular Interfaces

Anderson connectors create interchangeable power modules.

3 — Redundant Charging Paths

Energy can come from:

• alternator• solar• Jackery units• mains power

This improves reliability.

🚐 Final Technical Assessment

Vanilla now contains approximately:

4kWh of combined electrical storage

with multiple charging paths and modular connectors.

In electrical engineering terms the system behaves like a small off-grid micro-grid.

Energy can be generated, stored, transferred, and used in several ways depending on the situation.

That’s not just a campervan electrical system anymore.

It’s a mobile energy network.

And like all good engineering ideas, it works not because it’s complicated — but because it’s flexible, modular, and grounded in the physics of how electricity actually behaves.
