Upgrading an Existing Solar System with Battery Storage

Client Requirement

A homeowner recently contacted Fritts Solar to upgrade their existing solar system by adding battery storage. The customer already had solar panels and a non hybrid 5kW inverter installed by a previous installer and wanted to take advantage of the available battery rebate while maximizing the value of their current solar setup.

Their goal was to store excess solar energy produced during the day and use it later in the evening or during power outages, helping reduce electricity costs and increase energy independence.

Site Assessment & Findings

To ensure we recommended the most suitable solution, our team arranged a professional site inspection. During the visit, we carefully assessed the existing solar system, including the inverter and system configuration.

After a thorough evaluation, we identified that the current inverter was not compatible with battery integration. This meant that adding a battery directly to the existing setup would not be possible without upgrading to a hybrid inverter capable of managing both solar generation and battery storage.

Our team explained the situation clearly to the customer and recommended replacing the existing inverter with a hybrid inverter that could seamlessly support a battery system while continuing to utilize the already installed solar panels.

Our Recommended Solution

• 5kW Goodwe Hybrid Inverter
• 9.6kWh Goodwe Battery System

Location: Pebble Beach Blvd, Meadow Springs, WA, 6210

The GoodWe hybrid inverter allows the system to intelligently manage solar production, battery storage, and grid power in one integrated solution. This enables the customer to store excess solar energy and use it when needed, improving overall system efficiency and reducing reliance on the grid.

Addressing Customer Concerns

Initially, the customer was understandably hesitant about the additional cost involved in replacing the inverter along with installing the battery. Our team took the time to explain the long-term benefits of the upgrade, including improved system compatibility, better energy management, and the ability to fully utilize the available battery rebate.

To make the solution more accessible, we offered a competitive and affordable package that included both the hybrid inverter and battery system. After reviewing the proposal and understanding the long-term advantages, the customer felt confident in proceeding with the upgrade.

The Result

The installation was completed successfully, transforming the customer’s existing solar setup into a fully integrated solar and battery system.

With the new hybrid inverter and battery in place, the homeowner can now:

• Store excess solar energy generated during the day
• Use stored energy during the evening or peak electricity periods
• Reduce reliance on the grid
• Maximize the benefits of renewable energy incentives

The customer was extremely satisfied with the installation process and the performance of the upgraded system. As a result of the positive experience, she also recommended Fritts Solar to her brother and sister for their solar installations, reflecting the trust and confidence she had in our team and services.
