HOPE 5.0LW-B1

Store the sun.Power every moment.

A compact LiFePO₄ energy storage system designed to keep clean energy available long after the sun goes down.

Explore the systemView specifications

5.12 kWh rated capacity

BUILT TO SCALE

More solar energy.More independence.

Start with a 5 kWh system and expand as your energy needs grow.

  • 5.0 kWh usable capacity
  • Up to 48 units in parallel
  • Up to 240 kWh system capacity

ENERGY STORED INTELLIGENTLY

Daylight fades.Your power does not.

High energy density and up to 92% depth of discharge help make more stored energy available when it matters.

  • LiFePO₄ battery
  • Up to 92% DoD
  • Compact wall-mounted design

POWER THROUGH THE NIGHT

Clean energy,ready after sunset.

When night arrives, the home remains illuminated by energy captured during the day.

AFTER SUNSET

The sun goes down.Your energy stays.

Solar energy captured during the day remains available when your home needs it most.

ENERGY, STORED

Power waitingfor the right moment.

HOPE stores clean solar energy and makes it available quietly, safely, and efficiently.

READY WHEN NEEDED

From stored energyto instant light.

Reliable power after sunset, with up to 92% depth of discharge and scalable energy storage.

The system

One unit today. A whole energy strategy tomorrow.

HOPE 5.0LW-B1 stores what your array produces during the day and releases it when tariffs peak, when the grid falters, or simply when the sun has set. Each unit is self-contained and wall-mounted, so a first installation stays compact and a twentieth stays orderly.

Units link in parallel — up to 48 of them — which lets a single residential installation grow into a commercial one without replacing what is already on the wall.

Products

A battery to hold it. An inverter to place it.

Two Growatt units that cover a whole installation — storage on the wall and conversion beside it. Full specifications on each page.

HOPE 5.0LW-B1

A wall-mounted LiFePO₄ battery pack that stores what your array makes during the day and releases it after dark. One unit holds 5 kWh usable; up to 48 packs run in parallel, so the same hardware covers a house or a small commercial site.

  • 5.12 kWh rated capacity
  • 92% depth of discharge
  • ≥6000 cycles at 80% DoD

GrowattOff-grid and hybrid inverter

SPF 6000 ES-H

A 6 kW off-grid and hybrid inverter with two MPP trackers and a 500 V PV ceiling. It decides between solar, battery and grid on rules you set, drives two AC outputs for smart-load switching, and parallels up to six units as the site grows.

  • 6000 W rated output
  • 8000 W max. PV array
  • 2 MPP trackers

Installation

Mounted in an afternoon. Measured for decades.

The enclosure carries its own battery management, so commissioning is a matter of mounting, connecting, and configuring the parallel group. There are no fans to service and no scheduled maintenance windows to plan around.

Feasibility study

Size a system for your own site.

Tell us where the site is and how much land it has. We pull the measured irradiance and temperature for those exact coordinates from NASA POWER, size the array, and return the generation, cost and cash flow as a downloadable report.

Where is the site?
How much land is there?
The whole plot — we apply a packing factor to it.

Assuming 600W modules · 20% packing · $0.14/kWh tariff · 20-year study · 7-year loan at 12% · 10% discount rate. Open this to change any of it.

Irradiance and temperature come from NASA POWER for the coordinates you choose. Your location is only used to run this study.
