Make the Most of Your Solar Battery
Installing a solar battery system at home is a smart move, especially in Australia where sunlight is abundant and energy bills are rising. But even with the best solar products, power waste still occurs behind the scenes. Many homes unknowingly keep devices running that quietly drain electricity, reducing the efficiency and lifespan of their battery system.
In this blog, Solar Rains shows you which appliances to unplug or turn off to stop wasting stored energy and improve your return on investment. Let’s uncover the hidden power vampires lurking in your home.
Why Saving Power Matters with a Solar Battery
While your solar panels collect energy during the day, it’s your solar battery that keeps things running after the sun sets. But every watt counts. Any unnecessary load on the battery not only shortens backup duration but can also reduce battery cycles over time.
Lowering your energy usage means:
- Fewer deep discharges = longer battery life
- More energy available during peak hours
- Lower dependence on the grid
- Higher savings over time
Top Hidden Energy Wasters to Watch Out For
Here are the main culprits draining your solar battery when they don’t need to be:
Devices on Standby Mode (a.k.a. Energy Vampires)
TVs, sound systems, gaming consoles, microwaves, and even coffee machines draw power in standby, even when you’re not using them. It may be small per device, but together, they can drain up to 10% of your stored solar energy.
Tip: Plug them into a power strip and turn it off completely when not in use.
Old or Inefficient Refrigerators
Old fridges can use double the energy of newer, energy-rated models. If you have a second fridge in the garage “just in case”, it’s likely costing you hundreds per year in wasted power.
Tip: Consolidate to one fridge or upgrade to an energy-efficient model if it’s time.
Pool Pumps & Filters
These are one of the biggest energy consumers in Australian homes. If not scheduled properly, they may run during battery mode when you really need power elsewhere.
Tip: Program them to operate during daylight hours only, ideally when solar panels are actively generating power.
Heated Towel Rails & Underfloor Heating
Luxury features like heated bathroom accessories can quietly eat up power in the background, especially if left running 24/7.
Tip: Use timers or switch them off after a specific time window.
Plug-in Chargers Left Overnight
Phone, laptop, tablet and battery chargers left plugged in overnight continue to draw trickle power, even when the device is full.
Tip: Unplug or use smart plugs with scheduled off times.
Wi-Fi Routers & Modems
It may seem small, but routers running 24/7 consume more power than you think. If your household isn’t using the internet overnight, consider scheduling an off time.
Tip: Use a timer switch to automatically cut power from 1–5am (or any period of inactivity).
Outdoor & Security Lighting
These lights can consume significant energy, especially if not using efficient bulbs or if they’re left on due to faulty motion sensors.
Tip: Use LED bulbs and motion sensors properly calibrated, or integrate them into your solar monitoring system.
Old Halogen Bulbs
Halogen lighting is highly inefficient compared to modern LED lights. In large homes, outdated lighting can collectively draw significant energy.
Tip: Upgrade all your lighting to energy-saving LEDs for immediate battery gains.
Scheduling Appliances for Optimal Solar Usage
If you have a solar battery, timing is everything. Use heavy appliances like dishwashers, washing machines and dryers during the daytime when your solar panels are generating power, not after dark when your battery takes over.
Smart home energy management tools or programmable timers can help automate this.
How Cable Management Can Help
Proper cable management can also enhance battery system performance. Tangled or loose wires may result in inefficiencies, overheating, or safety risks.
Solar Rains recommends using:
- MC4 connectors for safe DC cabling
- Solar label kits to identify key system parts
- Cable trays & clips for a tidy and professional install

Tips for Maintaining Solar Battery Efficiency
- Monitor usage daily using your inverter app or system dashboard
- Check inverter logs for unusual power draws or usage spikes
- Regularly clean your solar panels for optimal input
- Schedule system inspections annually with your solar supplier

FAQs: Reducing Solar Battery Power Waste
No, fridges need to run consistently. However, upgrading to an efficient model or removing secondary fridges helps.
Yes. Smart plugs can schedule or remotely cut power to non-essential appliances, reducing phantom load.
Run major appliances during sunlight hours (10am–3pm), when solar panels produce power directly.
Absolutely. You can adjust backup thresholds and load priorities to minimise waste. Check with your solar installer.
Use a plug-in power meter or your system’s smart monitoring platform to track appliance usage.
Conclusion: Get the Most Out of Every Watt
A solar battery investment pays off best when paired with smart energy habits. By identifying hidden power wasters and scheduling high-energy appliances wisely, you extend your battery’s usefulness and reduce overall energy costs.
