✅ True energy independence – scalable from small cabin to large family home or farm
Systems sized 1.72 kW (small off-grid setup) to 20.64 kW (full home/farm with multiple appliances). Includes TBB hybrid inverter, LiFePO4 batteries, MPPT solar charging & all cables/mounts/safety gear. Add panels, batteries or generator later as needs grow.
TBB Power scalable 48V off-grid solar systems provide reliable, independent electricity for properties without mains power. Each package features a high-quality hybrid inverter with built-in MPPT solar charge controller, long-life LiFePO4 lithium batteries, pure sine wave 230 V AC output, and all essential wiring, mounts, fuses, breakers and safety components – ready for professional installation.
Systems scale seamlessly from 1.72 kW (weekend cabin, lighting & small appliances) up to 20.64 kW (large family home, farm, workshop or multiple buildings). The hybrid inverter intelligently manages solar input, battery charging/discharging and optional generator backup. Monitor performance, battery status & energy usage via Wi-Fi app. No noisy diesel generators, no fuel costs, no emissions – clean, silent power 24/7 with easy expansion as your needs increase.

Frequently Asked Questions
What size system do I need?
Depends on daily use: 1.72 kW for small cabin, 5 kW for family home, 20 kW for large property. Contact us for free sizing based on your appliances & location.
Can this run a home full-time?
Yes – 5–20 kW systems power typical off-grid homes (fridge, lights, TV, pumps, small cooking). Larger loads (electric oven) may need management or generator.
How long do the LiFePO4 batteries last?
5,000+ deep cycles (10–15 years typical use) – safer & more usable capacity than lead-acid.
Do I need planning permission?
Usually not for off-grid systems (no grid connection). Check local council for ground-mounted panels or visible roof arrays.
Can I expand the system later?
Yes – fully modular: add solar panels, batteries or inverters without replacing core components.
What happens on cloudy days?
Battery storage provides 1–2+ days autonomy. Optional generator auto-start for extended low-sun periods.
Who installs it?
Qualified off-grid/MCS-certified installer strongly recommended – includes safe 48V DC wiring, earthing & commissioning.
