Aspire 500-ES

Solar Energy Storage

The Aspire 500-ES is an off grid solar energy storage system for remote sites, roadside equipment and off grid infrastructure. A 500 Wp panel and two to five 48 Ah LiFePO4 modules inside the pole deliver dependable 24 V power with no grid connection.

Description

Aspire 500-ES solar energy storage system

The Aspire 500-ES provides reliable all night power where a grid connection is too costly or impractical. It pairs a 500 Wp monocrystalline panel with scalable LiFePO4 storage on a tapered, hot dip galvanised steel pole.

It is the Aspire 500 platform without the luminaire and LED arm: solar capture and battery storage only. Two to five 48 Ah modules (2,458 Wh to 6,144 Wh) sit secured inside the pole, with up to four on a 6 m pole. On slip base roadway poles the batteries are above the vehicle impact zone, and the dual battery management system switches off automatically in an impact.

Poles come in 6 m, 9 m and 10.5 m and are rated to Wind Region C (239 km/h). Options include a DC output for add on devices, a Bluetooth module for setup and diagnostics, and a pole mounted on/off switch. Each system carries a 5 year complete unit warranty.

Key Features

500 Wp solar capture. A single monocrystalline panel with stainless steel bird guards and optional panel guards.

Scalable LiFePO4 storage. 2 / 3 / 4 / 5 × 48 Ah modules of 1,229 Wh, rated for 4,000 – 6,000 cycles.

Secure in pole storage. Batteries sit inside the pole, with dual padlock plate and door locks.

Built for roadsides. Slip base poles keep the batteries above the impact zone, and the dual BMS shuts down automatically in a collision.

Poles from 6 m to 10.5 m. Hot dip galvanised tapered steel, rated to Wind Region C.

Optional power and control. DC output for add on devices, Bluetooth module and remote, and a pole mounted on/off switch.

Add lighting later. Fit an Aspire luminaire and it becomes an Aspire 500 street light.

(1) Autonomy and available capacity depend on location, load and configuration. (2) Controller rating only. Usable output depends on the number of battery modules, the autonomy required and whether the panel can recharge the battery at that load.

FAQ

What is the difference between the Aspire 500-ES and the Aspire 500?

The 500-ES is solar capture and battery storage only. Add an Aspire luminaire and LED arm and it becomes the Aspire 500 street light.

Where are the batteries?

Inside the pole base, secured and hidden. A 6 m pole holds up to four modules; 9 m and 10.5 m poles hold up to five.

How many nights will it run without sun?

An estimated 4 to 8+ nights, depending on load, the number of modules and location.

Which pole should I choose?

6 m suits most sites; 9 m and 10.5 m slip base poles suit roadsides and allow up to five modules. Foundations are confirmed against site ground conditions.

What maintenance does it need?

Very little. Clean the solar panel periodically; LiFePO4 modules last 4,000 to 6,000 cycles depending on use.
