Project Summary
SolarThoughts® recently completed a residential solar system upgrade in Queensland, replacing an ageing 5kW inverter with a Sungrow SH6.0RS 6kW Single-Phase Hybrid Inverter and installing a 16kWh Sungrow SBR Battery Storage System with backup power capability.
The project covered removing the old inverter, upgrading the DC strings, integrating the new hybrid inverter and battery system, configuring backup power for essential circuits, and commissioning the system. The homeowner now runs a more efficient, future-ready setup that captures more of their own solar energy, cuts grid consumption, and keeps essential appliances live during outages.
This is one example of the solar system upgrades we complete across Brisbane and South East Queensland. You can browse more of our completed solar projects for similar installations.

The Challenge
The homeowner had an existing 5kW solar system that no longer met the property’s growing energy requirements. The original inverter had reached the end of its operational life and offered no path to battery storage, which meant every unit of surplus daytime generation went to the grid for a low feed-in rate.
The customer wanted to replace the ageing inverter, add reliable battery storage, and keep essential circuits running during blackouts. They also wanted to lift self-consumption, reduce their electricity bills, and future-proof the home for higher demand and a possible EV charger installation later on.
Our Solution
After a detailed assessment of the existing installation, the SolarThoughts® team recommended the Sungrow SH6.0RS 6kW Single-Phase Hybrid Inverter paired with a 16kWh Sungrow SBR Battery Storage System.
Our installers safely removed the existing 5kW inverter and upgraded the DC strings to suit the new hybrid unit. We then mounted and commissioned the SH6.0RS, installed and configured the 16kWh SBR battery stack, and wired a dedicated backup circuit for essential household appliances. The job finished with full electrical testing, commissioning, and remote monitoring setup so the homeowner can track generation, storage, and consumption from their phone.
We completed the upgrade in accordance with Australian electrical standards and CEC installation guidelines. Every step follows the same process we use for solar inverter installation and solar battery installation jobs across the region.
Equipment Installed
Sungrow SH6.0RS 6kW Single-Phase Hybrid Inverter
The Sungrow SH6.0RS manages solar generation, battery charging, and grid electricity together, prioritising self-consumption while holding high conversion efficiency. It handles seamless battery integration, smart online monitoring, and backup power in a single single-phase unit, which makes it a strong fit for most Queensland homes moving from a legacy string inverter.

16kWh Sungrow SBR Battery Storage System
The Sungrow SBR stores surplus solar generated through the day so the household draws clean energy through the evening and overnight instead of buying it back from the grid. During an outage, the battery automatically supplies backup power to essential circuits.
The SBR uses a modular, stackable design, so capacity can be expanded later without replacing the system. It delivers high round-trip charge and discharge efficiency and pairs natively with the SH6.0RS.

Before and After the Upgrade
| Before | After |
| 5kW ageing inverter | Sungrow SH6.0RS 6kW Hybrid Inverter |
| No battery storage | 16kWh Sungrow SBR Battery System |
| No backup power | Backup power for essential household circuits |
| Limited energy flexibility | Intelligent hybrid energy management |
| Greater reliance on the electricity grid | Increased solar self-consumption and energy independence |
Benefits of This Solar Upgrade
Since commissioning, the homeowner stores surplus daytime solar rather than exporting it at a low feed-in rate, then discharges it through the evening peak. That shift is where most of the bill reduction comes from, and it also delivers backup power during grid outages and clearer visibility of system performance through remote monitoring.
The upgrade also improves the return on the original solar investment. The existing panels now feed a system that can actually use what they produce, and the modular battery leaves headroom for growing household demand or a future EV charger. If you want to model the numbers for your own home first, our solar cost calculator gives you a starting estimate.
Who Should Consider This Upgrade?
A hybrid inverter and battery upgrade suits homeowners with an ageing or faulty inverter, anyone wanting to add storage to an existing array, and households that need backup power through blackouts. It also makes sense if you plan to add an EV charger, or if you simply want to stop exporting cheap solar and buying it back at peak rates.
If your current system is underperforming rather than obsolete, solar panel repairs and maintenance may resolve the issue at lower cost. We assess both options before recommending an upgrade. Sizing matters just as much as brand, so read our guide on how to choose the right solar battery size before you decide on capacity.

Frequently Asked Questions
Can I add a battery to my existing solar system?
Yes. Most existing solar systems can be upgraded with a compatible hybrid inverter and battery after a professional assessment. We check your inverter model, string configuration, switchboard capacity, and available wall space before quoting.
Is the Sungrow SH6.0RS compatible with battery storage?
Yes. The SH6.0RS is built as a hybrid inverter and works natively with the Sungrow SBR battery range, delivering integrated energy management and backup power capability from a single unit.
What are the benefits of a 16kWh battery?
A 16kWh battery stores enough surplus solar to cover most of a typical household’s evening and overnight consumption, plus reserve capacity for outages. That lifts self-consumption significantly compared with exporting to the grid at current feed-in rates.
Will I still have power during a blackout?
Yes, on the circuits configured for backup. When we wire and commission backup circuits, the Sungrow hybrid inverter and SBR battery supply power to nominated essential appliances during a grid outage. Whole-home backup depends on your total load and requires separate assessment.
How long does a hybrid inverter and battery upgrade take?
Most residential upgrades of this type are completed in a single day on site, followed by commissioning and monitoring setup. Grid connection approval and any network paperwork happen before the install date.
