This is the story of two rooves. Its an epic saga about two different angles that will never meet but their love of each other is so great that it energizes a singular heart to take a client fully off grid....
Not sure where Im going with this. This is a powerhouse put in the heart of Welgemoed Belville.
Its a rolling array of 16 x Canadian 620wp (9.92kWp) combine with a Sunsynk 12kW Hybrid single phase lynk. and a 16kWh Sunsynk lithium battery.
Client is fully off grid and smiling his way to a cost free, stable home power supply.

We’ve just finished building one of the most sophisticated yet user-friendly solar system calculators available online today.

👉 https://gwstore.co.za/system-designer-calculator/

It’s now easier than ever to calculate what size solar system you actually need — without needing to be a solar expert.

If you’re thinking about installing a new solar system or upgrading an existing one, give it a try. The calculator will help you understand:

The correct inverter, battery and solar panel requirements
Your realistic solar generation potential
Your expected return on investment
A clear summary of the system that best matches your requirements

It’s completely free to use, designed for South African conditions, and built to give you useful, realistic information rather than simply trying to sell you the biggest system possible.

Give it a go and let us know what you think.

Use our solar system calculator to estimate the inverter, solar panel and battery size you need based on your energy usage in South Africa.

Aish. I feel so bad for JHB city power. They are going the way of the dinosaur. Especially for their residential/commerical clients. Just look at this install below. What could possibly be better? It adds value to your house. It recovers its costs. In fact its one of the only purchases you make that will actually recover its costs. It protects you from cable theft and grid outage. Solutions like this are the future and a decentralised grid is just more efficient.🔥
This Randburg install looks so good. Its a Sunsynk 8kW hybrid, with a Sunsynk 16kWh lithium battery (best value purchase) and 14 units of JA Solar 620wp panels. 🌞🌞

Thanks to JHB install team Tim & Co Energy. Beautiful work as always.

Hi everyone 👋

We’ve just launched our new Solar Battery Calculator on the GW Store Renewables website:

🔋 https://gwstore.co.za/solar-battery-calculator/

The new calculator is designed to be simple, intuitive and user-friendly, particularly for people who may not have a technical solar background. It helps you work out your battery requirements and guides you towards choosing the right equipment for your needs.

Now we need some help testing it!

When you build something yourself, it’s very easy to overlook mistakes or keep repeating the same testing scenarios. If you have a few minutes, we’d really appreciate it if you could give the calculator a try.

If you spot any errors, strange results, miscalculations or anything that simply doesn’t make sense, please let me know in the comments or send me a DM.

Online solar battery calculator. Helps you work out your requirements and coverts to number of batteries required.

Absolute behemoth of a system designed and installed to surgically remove the client off Moorreesburgs costly electrical grid. The roof was technically challenging and the array had to be moved from the West to a slightly compromised North but generation looks good.
This client went fully off grid the day after the two Sunsynk 16kWhs lithim batteries were fully charged and his power house of 27 x Canadian 620s (16.74kWp) hit is Sunsynk 16kW hybrid inverter.
We are grateful to this client for his attention to detail and in his care we completed to perfection.🔥🔥🔥

Due to our crazy busy schedule we had to bring in our Eastern Cape team to assist with this install in Velddrif, Port Owen and were not disappointed. Thank you to Manu and team for your amazing work.
This is a Deye 8kW with 3 x Dyness 5.12s (15.36kWh) and 12 x Jinko 620s. Nice neat power hub where you need it most. 💪💪

Lookie here. The sun sets over a very very very attractive ground mount install for all of 12 panels. Its one of those installs that you could spend time just staring at its splendour.
This kit form ground mount system holds 7.44kWp of JA Solar 620s and in this case paired with a Sunsynk 12kW 3Ph hybrid and 2 x Volta Stage 3 (20.48kWh). The East London coast sunsets have never looked so pretty.
Thanks to our top national installer Hans Cotte and his team of merry men. As usual delivered and installed perferctly.

It's been a while since we've installed one of these.

The Sunsynk Lynk isn't my personal favourite inverter platform—we've always been fans of the more traditional Sunsynk range. That said, it's important to note that this isn't because it can't do the job. In my experience, the remote settings and commissioning process are a little less intuitive, making installation slightly more technical than usual.

Once it's commissioned properly, however, it's a very capable machine.

Pair it with what I consider one of the best batteries on the market—the 16kWh Sunsynk battery 😍—and add a pounding pocket of 12 x JA Solar 620W panels, and this 12kW single-phase hybrid system becomes an absolute powerhouse.

This client is a valued repeat customer, and this marks the third system we've installed for him. We genuinely appreciate the continued support and are always proud to deliver a system built for performance, reliability, and long-term value.
