In 2025, smart energy isn’t just about storing solar — it’s about using your battery to make smarter financial decisions. With Redx AI, your home battery can now participate in real-time energy trading, buying low and selling high — automatically.
Let’s explore what energy arbitrage really means, how it compares to standard feed-in or VPP programs, and how Redx AI takes the thinking out of it.
What Is Energy Arbitrage?
Energy arbitrage is a strategy that lets you charge your battery when electricity prices are low (or even negative), then use or export that energy when prices are high. It’s a way to earn or save more — using timing instead of just volume.
How is it different from just exporting to the grid?
Standard Feed-in Tariff (FiT):
You sell excess solar to the grid at a fixed low rate (e.g. 5–10c/kWh), no matter when you export.
Virtual Power Plant (VPP):
You give control of your battery to an energy company, which can export power when it’s good for them — you get a cut, but less control.
Energy Arbitrage with Redx AI:
You stay in control. Redx AI watches real-time wholesale prices every 5 minutes and decides whether to buy from the grid (when prices are low or negative) or sell energy back (when prices spike). That’s buy low, sell high — automatically.
What about negative prices?
Yes, negative electricity prices do happen — especially during the day when there’s lots of solar generation and low demand. That means the energy market is paying people to use electricity, not produce more of it.
Redx AI takes full advantage of this in two smart ways:
- Smart Charging:
It charges your battery from the grid when prices are negative — meaning you’re getting paid to store energy. - Smart Export Blocking:
If your battery or solar system is set to export when prices are negative, you could be penalised (essentially paying to export energy).
Redx AI detects this and automatically stops exporting when prices fall below zero — protecting you from losses.
This dual approach ensures you’re never exporting at a loss and always charging when it’s most profitable. That’s real-time energy intelligence you won’t get from a standard battery system.
How Redx AI Automates Energy Trading
Redx AI connects your battery to both the wholesale electricity market and your home’s energy usage in real time.
Here’s what it does 24/7 — so you don’t have to:
1. Real-Time Price Monitoring (Every 5 Minutes)
Redx AI taps into the National Electricity Market (NEM) and checks pricing data at 5-minute intervals — watching for sudden price drops or spikes.
2. Predictive Energy Use Modelling
It learns your household patterns — when you use power, when your solar exports, and when your battery is needed.
3. Smart Charging Logic
If the price is low (or negative), Redx AI charges the battery — either from solar or from the grid.
4. Profitable Exporting
When wholesale prices surge (e.g. during heatwaves or early evenings), Redx AI exports battery power back to the grid at those high rates — even earning more than traditional feed-in tariffs.
5. Zero Manual Effort
You don’t need to watch the market or guess the best time. Redx AI handles it all automatically — saving you money while you sleep.
Why This Matters for Your Bills
- Lower electricity costs through precise timing
- Profit from price spikes, not just avoid them
- Smarter use of your battery = faster return on investment
- Hands-free optimisation, no babysitting your energy usage
Whether you’re trying to lower bills, go greener, or earn from your solar investment — Redx AI gives your battery real intelligence.
FAQ – Redx AI & Battery Energy Trading
Q: What’s the difference between Redx AI and a Virtual Power Plant (VPP)?
A: Redx AI keeps you in control. VPPs hand battery control to an energy provider. Redx lets your battery trade based on your own advantage.
Q: Can Redx AI really buy electricity at negative prices?
A: Yes. In the wholesale market, prices sometimes drop below $0. Redx AI automatically buys energy at those times to charge your battery.
Q: Do I need to monitor the market myself?
A: Not at all. Redx AI tracks prices every 5 minutes and automates all buy/sell decisions for you.
Q: How much can I save or earn with energy arbitrage?
A: It depends on your battery size, usage, and price events — but many customers see a noticeable drop in bills and even earn monthly credits.
