Hello Powerforum members,

Hubble Energy will be sending me one Hubble Energy AM16+ (16.1kWh) and one AM5+ (5.12kWh) for extended real-world testing and review.

These are part of their current LV Range which includes:

• AM-2 – Popular 5.5kWh 51V NMC battery 1C rating, proven long-term performer.

• AM-4 – Compact 2.56–2.75kWh 25.6V wall-mount battery with 1C rating.

• AM-5+ – 5.12kWh 51.2V LFP with built-in Cloudlink, 1C rating and RGB display.

• AM10+ – Larger 10kWh+ model in the + series with advanced features.

• AM16+ – High-capacity 16.1kWh floor-standing LFP with wheels, built-in Cloudlink and high discharge capability.

• S-100A – 12V 100Ah (1.2kWh) compact lithium battery.

• X-5+ (New X-101) – Newer generation Rack Mounted 5.5kWh model with updated features.

• X-101 – Established Rack Mounted 5.5kWh 51V model, widely used in hybrid systems.

Note:

Hubble Energy also has a very exciting HV Range, but this review will focus 100% on the LV Range especially for members who already own Hubble batteries or are considering them.

Hubble Energy will also soon release the new AM-2+, which keeps the same NMC technology as the existing AM-2 models but adds built-in Cloudlink and several extra features.

My Setup:

• Main system: Solis S6 8kW Pro Hybrid (master) with a Solis S6 6kW Pro seeing the 8kW as “grid”

• AC-coupled: Enphase micro-inverters + Solis S5 4.6kW grid-tied inverter on the Aux port of the 8kW

• 2kW Wind turbine on the Solis S6 6kW MPPT in constant voltage mode

• Separate Solis 5kW Off-Grid inverter for additional testing

• Existing battery bank: 7 × Hubble AM2 (mixed ages – oldest >5 years old)

AM2 cycle counts right now:
1411 | 1036 | 880 | 853 | 805 | 737 | 595 cycles Total bank health still at 99% – very impressive for the age mix.

What I’ll be Testing:

• Daily cycling and performance of the AM16+ and AM5+ on the Solis S6 6kW and the 5kW Off-Grid inverter

• Parallel operation between the new + series and my existing AM2 bank (old model compatibility is a big claim)

• Mixing different aged AM2 batteries and different capacities with the new units

• Compatibility with multiple inverter brands/configurations

• Cross-brand testing – insider info from a senior Hubble engineer says the new Plus range can work with almost any other battery brand

• Full use of the built-in Hubble Cloudlink (I have unit #388)

I’ll also be highlighting the exciting new ergonomic and safety features:

• Wheels on the AM16+ for easy movement

• Magnetic panels that neatly hide all internal cables

• Front-accessible BMS and critical components for simpler maintenance

• Active cooling, fire suppression, and more

The unlimited cycle warranty on these new models is particularly attractive and will be closely monitored during long-term testing.I’ll be doing a detailed initial short-term review followed by ongoing long-term data over the coming months.

Expect real numbers on efficiency, temperature performance, charge/discharge behaviour, Cloudlink functionality, noise, installation, display readability, and real-world interaction with wind + AC-coupled solar.

We will also speak nicely to Hubble Energy and ask if they can provide some products for a lucky draw / giveaway for Powerforum members.

If you have any testing requests (particular charge profiles, high-load scenarios, Cloudlink screenshots, parallel comms behaviour, etc.), please reply in this thread. I’ll try to cover as many as possible.

This should be a very thorough and transparent review for the Hubble community.

Looking forward to sharing the results with everyone.

Cheers, @Powerforum Store

Hello Everyone Just received the Hubble AM16+ and the AM5+ will unbox them this weekend share pics of what's in the boxes. I can however say both batteries are really Heavy already a good sign the AM5+ is almost 60KG and the AM16+ cardboard box almost 160KG wooden crate packaging included... all came on a pallet.

I will need extra hands to move that beast into place the good news is that it has wheels.

Exciting stuff will get some feedback from the Hubble engineer on how to make 3 Cloudlinks talk to each other considering the batteries have their own built in units.

Also get the new batteries to talk to the old AM2 Units...

Then I will start playing around with the batteries and get some meaningful testing done may even be able to share live viewing access to the two cloudlinks with links here on the forum.

Will keep you posted this weekend is unboxing and installing.
