HI Series floor-standing IP65 LiFePO4 battery, 14.3–16.1 kWh

A 900 mm wide, 175 mm deep slab of a battery — IP65, 200 A BMS, and low enough to slide under a window or stand against an outside wall.

A battery shaped like a wall panel

The HI is 900 mm wide and 175 mm deep. That shape is unusual for a floor-standing battery, and it exists for one reason: to fit where a conventional cabinet cannot — under a window, along a corridor wall, behind a door, or against the outside of a house where the inverter already is.

The cells sit in a single plane with the BMS and terminals at one end. That layout is why the enclosure can be sealed to IP65 without a fan: there is no internal air path to filter.

IP65 in practice

The rating is dust-tight and protected against water jets, which covers rain on a sheltered wall, hose-down cleaning in a workshop, and the salt haze of a coastal site. It does not cover immersion, and it does not cover direct sun: a black enclosure in August will exceed the 45 °C charge limit and the BMS will refuse to charge until it cools.

Mount it on a 100 mm plinth, face it away from the afternoon sun, and bring the DC cable in through the bottom gland so water runs away from the entry.

200 A at 51.2 V

The 200 A BMS puts the HI in the 10 kW inverter class. For a whole-house system with a heat pump that is the right pairing: 16 kWh of storage and a 10 kW inverter covers the evening peak and the morning recovery without generator support.

Key Features

  • IP65 protection rating — dust-tight and hose-proof
  • 51.2 V, 280 and 314 Ah — 14.3 and 16.1 kWh
  • 200 A BMS, suitable for 10 kW-class inverters
  • Only 175 mm deep, 900 mm wide — slides into narrow spaces
  • Floor-standing with wall anchor points
  • 8,000 cycles, 5-year warranty, 10+ year design life
  • Smart BMS with all-round protection for unattended sites
  • CAN and RS485 communication with hybrid inverters

Applications

Outdoor solar installations

IP65 means it can stand against an outside wall under an eave, avoiding a cable run back into the house.

Dusty or wash-down environments

Agricultural sheds, workshops and coastal sites where a vented indoor cabinet would fill with dust or salt.

Narrow plant rooms

175 mm deep and 900 mm wide — under a window, along a corridor, behind a door.

FAQ

Can it really go outdoors?
Under an eave or in a ventilated outdoor cabinet, yes. Direct sun will push cell temperature above the charge limit in summer, and standing water will eventually find a gland — mount it on a plinth.
Why is it so wide and shallow?
The cells are laid out in a single plane to keep the depth at 175 mm, which lets the battery go where a cabinet cannot. Plan 900 mm of wall length.
What is the weight?
131 kg for the 280 Ah model and 132 kg for the 314 Ah. Two people with a pallet truck can position it; the floor must be level.
Does IP65 affect service access?
The front cover is gasketed and opens with four fasteners. Re-seat the gasket and torque the fasteners evenly, or the rating is lost.
