1. Outstanding value. Fogstar is one of the most affordable lithium batteries on the market for its capacity, so your money buys more usable storage.
2. Proper cells. Fogstar uses genuine LiFePO4 cells, the safe, long-life battery chemistry, not a budget shortcut.
3. A proven inverter. Victron inverter/chargers have a long track record in demanding off-grid and marine use, so the brains of the system are as reliable as they come.
4. Big, expandable capacity. Fogstar batteries stack, so you can build a large storage bank now or add to it later.
5. Proper monitoring. The Victron VRM portal lets you and us keep an eye on performance and spot anything unusual early.
Victron’s VRM online portal and app let you watch your solar, battery and home usage in real time from your phone. Pair the system with a smart tariff and it charges when electricity is cheapest, then powers your home through the expensive evening peak. We set this up and walk you through it at handover.
We fit several battery brands, and we recommend the Fogstar and Victron combination for homeowners who want maximum usable storage for their budget. It suits you well if:
If an all-in-one system suits you better, we will say so and point you to one.
Yes. Around 40% of the battery systems we fit in North Wales are retrofits to existing solar. The Victron inverter/charger sits alongside your current setup and manages the Fogstar battery, storing the excess energy your panels already produce for use in the evening. We confirm the best way to connect it at the survey.
A battery is only as good as the install behind it, and pairing two brands well takes experience. HSB Renewables has fitted renewable systems across the region for over ten years, and we are a Which? Trusted Trader and RECC member. We handle everything from survey and design through to installation, commissioning and aftercare.

Why pair Fogstar with Victron?
Fogstar makes excellent-value lithium batteries but does not make an inverter, so the battery needs one to work in your home. Victron inverter/chargers are among the most reliable available, which makes them a natural partner for Fogstar’s low-cost storage.
Is Fogstar a good battery?
Yes. Fogstar uses proper LiFePO4 cells and has quickly become one of the most popular value battery brands in the UK. It gives you a lot of usable capacity for the money.
Can I add this to my existing solar panels?
Yes. We can retrofit a Fogstar and Victron system to most existing solar arrays, or supply it alongside new panels.
How big can it go?
Fogstar batteries stack, so we can build anything from a single 5kWh unit up to a large storage bank. We recommend the right size at your free survey.
What warranty do I get?
Fogstar batteries carry an 8 to 10 year warranty depending on the model, and Victron inverters are known for their long service life. We register your warranties on your behalf.
