Frequently Asked Questions
Absolutely. Larger battery systems can help businesses reduce peak demand charges, cut energy costs, and improve resilience during outages.
Yes, but having a smart meter ensures you can benefit from export tariffs (like SEG) for any excess energy you send back to the grid.
Solar batteries are generally maintenance-free. However, we recommend periodic system checks to ensure optimal performance.
Yes. Modular systems like Dyness, Fox, and Sigenergy allow you to add more storage as your energy needs grow.
Charging times depend on battery size, inverter type, and sunlight availability. Most home batteries charge fully within a few hours of good solar generation.
By storing excess energy for later use, you can reduce reliance on the grid and save up to 90% on electricity bills.
Yes, if your system includes backup functionality. Batteries like Tesla Powerwall 3 can provide off-grid support during outages.
Most batteries last 10–15 years, depending on usage and brand. Warranties usually cover 6,000+ cycles.
Yes. Many batteries can be retrofitted to existing solar PV systems, especially with hybrid inverters.
The right battery size depends on your energy usage and solar system. Our experts will recommend the best option after a consultation.
