Tower LiFePO4 Battery 14.3–32.2 kWh for Solar Storage

The high-capacity single cabinet

Between 15 and 30 kWh, the choice is usually between stacking several small modules and buying one large cabinet. The HF takes the second route: a single tower, one BMS, one set of terminals, one breaker. Fewer connections means fewer failure points, and a service visit opens one cover rather than four.

The tower carries 280 Ah to 628 Ah cells at 51.2 V. The largest pair, 560 and 628 Ah, are 220 kg cabinets on castors — moving one across a garage floor is a two-person job with a pallet truck, not a lift.

Current, surge and inverter matching

200 A continuous at 51.2 V is just over 10 kW. That covers most whole-house inverters in the 5–10 kW class with headroom for surge. If the inverter is larger, parallel a second tower rather than pushing a single BMS beyond its rating — the BMS will derate on temperature before it trips, and a derated battery looks like a failing battery to the customer.

Thermal behaviour

LiFePO4 tolerates a wider temperature band than lead-acid, but the top of the charge curve is where heat matters. In a garage that reaches 35 °C in summer, mount the tower away from the inverter's exhaust and leave 100 mm behind the cabinet. The BMS reports cell temperature over CAN; if the inverter supports it, set the charge current to drop above 40 °C rather than waiting for the BMS to act.

200 A continuous charge and discharge

LCD display with CAN and RS485 ports

Grade A cells, 8,000 cycles, 5-year warranty, 10+ year design life

Bluetooth and Wi-Fi monitoring standard

Wall-standing design, 286–326 mm deep

Applications

Whole-home backup

32.2 kWh covers a house with a heat pump through an evening and a cloudy morning without generator support.

High-surge off-grid

200 A at 51.2 V is 10 kW continuous — enough for a pump start on an off-grid property.

Small commercial storage

Two towers in parallel give 64 kWh for a shop or clinic, in a footprint smaller than a cabinet.

FAQ

How tall is the tower?

800 mm for the 280 and 314 Ah modules, 960 mm for the 412 Ah and 990 mm for the 560 and 628 Ah modules. All are under a metre, so they fit under a worktop or beside a door.

Does it need a plinth?

No, but it must stand on a level, load-bearing floor. Anchor the top to the wall where the site has seismic requirements or where children or trolleys pass.

Can I add capacity later?

Yes — parallel a second tower. Keep the DC cable lengths equal so the two towers share current evenly.

What is the difference from the HH vertical series?

The HF is a single tall cabinet with the largest cells; the HH covers a wider capacity spread in a slightly different case profile. Choose on footprint and capacity, not on technology — both use the same BMS family.
