If you have been looking into battery storage, you have probably come across the question of which battery works with which inverter. It sounds like a technical detail, but it is actually one of the most important decisions in any storage installation. A battery and inverter that are not properly integrated can mean poor communication between the two, inaccurate state-of-charge readings, inefficient charging, and a system that does not perform as expected over time.
That is why Fogstar’s announcement that their full battery range is now officially integrated with LuxpowerTek inverters is worth paying attention to, particularly for customers considering battery storage as part of a new installation or looking to retrofit storage onto an existing solar setup.
How the integrated system works
One supply chain. One support contact. Verified compatibility from day one.
What Fogstar and LuxpowerTek have announced
Fogstar have become the official UK distributor for LuxpowerTek inverters, and their full battery range, from the 5.12kWh rack unit up to larger capacity systems, is now officially approved for integration with LuxpowerTek hardware. This means installers and customers can specify a Fogstar battery and a LuxpowerTek inverter as a fully compatible, end-to-end system supplied through a single UK-based source.
Fogstar have also launched a branded inverter range built on LuxpowerTek technology, designed to pair physically and technically with their battery systems. These carry a 10-year manufacturer warranty and are available alongside the battery range as a complete package.
Who is LuxpowerTek?
LuxpowerTek is not a new name in the energy storage sector. The company has over 20 years of experience in intelligent energy solutions and has deployed more than 350,000 systems across residential, commercial and off-grid markets worldwide. They are known for producing inverters that perform reliably in real-world conditions rather than just in controlled test environments, which is a distinction that matters once a system is installed in a Devon home and expected to run quietly for a decade or more.
Their range covers hybrid systems, which handle solar, battery, grid and backup loads through a single unit, as well as off-grid inverters for properties not connected to the grid or looking for greater independence from it. The LuxpowerTek GEN-LB-EU hybrid is available in 8kW and 10kW ratings, accepts up to 9kW of solar input, and is rated IP66 so it can be mounted indoors or outside without issue.

Why integration matters in practice
When a battery and inverter are officially integrated, the two components communicate directly and accurately. The inverter knows precisely how much charge is in the battery, controls charging and discharging to optimise performance and battery life, and responds correctly when solar generation changes, grid power is needed, or a backup situation arises.
Without official integration, this communication can be approximate or unreliable. Some combinations work well in practice, but others produce problems that are difficult to diagnose: the battery reading incorrectly, the inverter not knowing when to stop charging, or the system behaving unexpectedly during a power cut. A manufacturer-approved pairing removes that uncertainty from the outset.
In plain terms: a Fogstar battery paired with a LuxpowerTek inverter gives you accurate state-of-charge reporting, optimised charge and discharge control, and efficient battery management system communication. Everything works together as it should from day one, with one supplier and one support structure behind both components.
How this fits with our work at Electrix Renewable
We have written previously about our relationship with Fogstar as a supply partner for lithium battery storage installations in Devon. The LuxpowerTek partnership strengthens that offering because it means we can now specify a complete Fogstar system, battery and inverter together, from a single UK-based supplier with a single support structure behind it.
For customers planning a new solar and battery installation, or wanting to add battery storage to an existing solar system, this kind of end-to-end compatibility is genuinely useful. It simplifies the design process, reduces the number of warranties and support contacts involved, and means the system is built on components tested and approved to work together.
Fogstar batteries remain compatible with a wide range of other inverters including Sunsynk, Solis, Victron and Growatt, so the LuxpowerTek partnership is an addition to the options available rather than a restriction. We will always recommend whichever combination makes most sense for your specific property, setup and budget.
We also install sodium battery systems through our partnership with Eleven Energy, which offer different characteristics, particularly around cold-temperature performance and sustainability credentials. If you are weighing up lithium against sodium, we can walk you through the comparison when we visit for a survey. You can also read more about our approach to lithium battery storage and our work with Fogstar in our earlier blog post.
