Pick your worst load
The container office. The night works. The hand tools three floors up. Whichever one has a generator idling at 30 per cent just to keep it alive.
Singapore's own portable BESS · mobile battery power
Industrial-grade portable BESS. Engineered in Singapore, built by one builder for another.
We are not importing somebody else's by-product and putting a Singapore sticker on it. The EH-Series battery energy storage system was designed here, and every revision of it came out of a real review from a real site: the operator who said the handle was in the wrong place, the foreman who needed a different socket, the safety officer who wanted the panel moved. From 5 kWh to 500 kWh, built by people who have stood on the site it is going to.
Under 50 dB(A)
Zero emissions on site

Battery generators to containerised BESS
Anyone can import a battery. We engineered one for Singapore.
Why we exist
Diesel is running out of road. Most "portable power" was never built for this.
Night works next to housing. Fit-outs inside a live building. Fuel that has to be stored, guarded and topped up at 2am. Tenders that now ask about emissions before they ask about price. The generator that solved all of this for forty years is quietly becoming the thing that loses you the job.
The usual alternative is a battery in a box, shipped in from overseas, with a manual written for another country and a support desk eight hours behind you. When it trips on a Saturday, nobody local can tell you why.
That gap is the reason this company exists.
Decentralised site power
Instead of pulling wires, we bring the power next to you.
On most sites the real cost is not the generator. It is the cabling. Long runs from a single supply point, trip hazards through walkways, cable that has to be laid, protected and moved again next week, and an electrician booked before anyone can start.
A portable BESS removes that problem by putting the power source at the work face. The unit goes where the tools are: down in the basement, up on the deck, inside the tunnel, beside the gondola. No trenching, no temporary distribution board, no waiting on an infrastructure upgrade.
Our own platform
The EH-Series. Ours by design, not by purchase order.
Most portable BESS in this region is bought from a factory overseas and resold with a new sticker. The EH-Series is different. We designed it, we localised it for Singapore conditions, and in April 2026 we filed a patent application covering the innovation behind it.
A reseller has to email a factory and hope. We just do it.
- Patent pending. Application filed April 2026
- Localised. Engineered and documented for Singapore industrial sites
- Configurable. Output, capacity and form factor to suit the deployment
- Supported here. Spares, service and engineering response in Singapore
One partner, the full range
Mobile battery energy storage from 5 kWh to 500 kWh, from the same team.
You should not have to change supplier because the project got bigger.
5 to 8 kWh
Portable battery generators for tools, lighting and small sites
20 to 30 kWh
Stacked and cabinet BESS for industrial loads and backup power
Up to 500 kWh
Containerised battery energy storage for site-wide power and peak demand
Hybrid
Battery working alongside grid, generator or solar
The difference
There is no second version of what we do.
We do not need to name competitors. The comparison speaks for itself.
| An importer or reseller | Energy Revolution Engineering | |
|---|---|---|
| The product | Bought from an overseas factory, rebadged | The EH-Series, our own design, patent pending |
| Compliance | Documentation written for another market | Built and documented for Singapore sites |
| Modifications | Email the factory. Wait. Usually no. | We hold the drawings. Usually yes. |
| Sizing | Sells you what is in the container | Sized from your actual load and runtime |
| Cabling | One supply point, long runs, more cable | Power delivered at the work face |
| Range | One or two models | 5 kWh to 500 kWh, plus partner products |
| When it faults | A support ticket in another time zone | The engineer who commissioned it |
| Backing | Whatever the local entity can carry | Systems integrator arm of GoRental Global |
Strategic appointment, effective 1 September 2025
Engineering depth meets regional deployment scale.
Energy Revolution Engineering has been appointed as GoRental Global's systems integrator for the commercial and industrial sector.
ERE leads the technical front, translating complex site loads, operating conditions and project constraints into integrated battery energy storage solutions. GoRental Global drives market expansion and large-scale deployment across Singapore and Southeast Asia.

In the media
Featured in The Business Times.
"Created in collaboration with Energy Revolution Engineering, the EH-ONE+ was made to comply with Singapore's safety and regulatory standards."
The Business Times, 18 June 2026. The feature reports that switching from generator sets to the EH-ONE+ can lead to cost savings of 40 to 50 per cent while maintaining uninterrupted power supply on site, and that these battery energy storage systems have prevented 1.5 million kilograms of carbon emissions to date.

Make the switch
You do not have to believe any of this. Put one unit on one site.
Nobody changes their site power strategy because of a website. So we are not asking you to. We are asking for one load, on one site, for one month. Keep the generator. Keep the programme. Change nothing else.
We size it and deliver
Our engineers profile the load, specify the battery energy storage system, deliver it and commission it on site. Your operators are trained before we leave.
Read the numbers yourself
Generator runtime, litres burned, refuelling trips, noise complaints. If the numbers do not move, you have lost a month and nothing else.
Nothing to rip out
Hybrid means the generator stays. The battery simply takes the loads it should never have been running.
Rent it first
Trial deployment before any commitment, structured through GoRental Global. Buy later if it earns its place.
Same working day reply
Send the equipment list. You will have a real sizing answer back from an engineer, not a brochure.
Deployment as quick as same day
Fleet units are charged and ready. When the dates are tight, that is often the difference.
Every contractor on this page started with one unit on one site.
Tell us the load. We will tell you the system.
What needs powering, for how long, and when. That is enough for us to come back with a real answer. Our fleet is finite and the good dates go early, so if your project has a fixed start, talk to us before it is urgent.
