Exciting Long-Term Review: NEW Hubble Energy AM16+ & AM5+ in a Real Micro-Grid Setup

5 hours ago5 hr

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.

Hubble Energy

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.
