Thanks for Pointing out my error. Fair point Knyee isn’t a household name here in SA yet. They’re the residential ESS brand of Chilwee Group (Chaowei), one of China’s biggest battery manufacturers: founded 1998, Hong Kong listed, 30+ factories, 100+ subsidiaries, and tens of thousands of employees. They produce on a scale that dwarfs every local South African battery brand combined many more known brands likely come out of their factories. The ES-LV-16 is essentially their flagship low voltage floor standing model coming out of that industrial base. The same factories also supply white label versions like certain Hina ESS units that typically run a scaled down version of the Knyee Energy BMS while the cells and internal components are the same.

Very Interesting to see how creative one can be with off grid systems the Solis does indeed make things more flexible and eliminates the need to have loads on seperate feeds I have been Off Grid for many years now and my generator is still brand new I dont think it has done more than 2 Hours running time Since I bought it never had grid to start. What I find impressive with the Hubble setup is that even though i am running a 16KW and a 5KW batteries together they charge and discharge in ratio and maintain decent SOC balance with each other through out the charge and discharge curves. This weekend I plan to do the full inverter integration with Solis cloud had a few special cables I needed to make up this potentially will allow me to monitor the Solis inverters in real time on the Hubble Cloudlink portal this is very useful when monitoring wind power production and realtime loads on the inverters will also provide some nice data to analyse.

Hello All here is an update on my review thus far and the block diagram requested by @Yellow Measure System Update – Current Operating Mode + Parallel Performance Here’s a clear overview of how the system is currently configured and performing: Current System Layout Solis S6 8kW Pro (Master / Grid-forming) Battery: 7 × Hubble AM2 (≈30 kWh) PV array charging its own battery bank Solis S5 4.6kW AC-coupled via the Aux port Solis S6 6kW Pro (sees the 8kW as “Grid”) Battery: AM16+ (16.1 kWh) + AM5+ (5.12 kWh) running in parallel (≈21.2 kWh total) 2 kW Wind turbine on the MPPT (constant voltage mode) “Allow Grid Charge” is enabled with a timed schedule Night-Time Priority Operation From 17:00 to 08:00 the 6kW inverter carries 100% of the house loads. As a result the 8kW battery bank stays completely idle overnight (zero discharge). At 08:00 the 6kW stops injecting. By that time solar production has already started, so the PV on the 8kW essentially carries the daytime loads and the older AM2 bank still sees very little (or zero) discharge. This is a very elegant way of prioritising the newer LFP batteries at night while protecting the older AM2 bank.Parallel Battery Performance (AM16+ + AM5+)The two batteries are charging and discharging proportionally. Their State of Charge stays within 1% of each other throughout the entire charge and discharge curve across multiple cycles. This is excellent balancing behaviour and shows that the Cloudlink / BMS communication between the different capacity packs is working very well. ┌─────────────────────────────────────────────────────────────────────────────┐ │ MICRO-GRID SYSTEM │ │ (Current Night-Time Priority Operating Mode) │ └─────────────────────────────────────────────────────────────────────────────┘ ┌──────────────────┐ │ HOUSE LOADS │ └────────┬─────────┘ │ ┌────────────────────────┴────────────────────────┐ │ │ ▼ ▼ ┌───────────────────────────────────┐ ┌───────────────────────────────────┐ │ SOLIS S6 8kW PRO HYBRID │ │ SOLIS S6 6kW PRO HYBRID │ │ (Master / Grid-Forming) │◄── sees as │ (Sees 8kW as “Grid”) │ │ │ “Grid” │ │ │ Battery: 7 × AM2 (≈30 kWh) │ │ Battery: AM16+ + AM5+ Parallel │ │ │ │ (≈21.2 kWh) │ │ • PV charges its own battery │ │ • “Allow Grid Charge” = ON │ │ • Completely IDLE at night │ │ • Timed charge schedule │ │ (zero discharge) │ │ • From 5 PM → 8 AM carries │ │ • Only starts bearing load │ │ ALL the house loads │ │ at 08:00 when 6kW stops │ │ │ │ injecting │ │ │ │ • By then PV is already covering │ │ │ │ most/all of the load │ │ │ └──────────────┬────────────────────┘ └──────────────┬────────────────────┘ │ │ │ │ ┌─────────┴─────────┐ ┌─────────┴─────────┐ │ │ │ │ ▼ ▼ ▼ ▼ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ ┌─────────────────┐ │ PV Array │ │ Solis S5 │ │ 2 kW Wind │ │ Hubble Cloudlink│ │ (charges │ │ 4.6 kW │ │ Turbine │ │ (on both │ │ AM2 bank) │ │ (AC-coupled│ │ (on 6kW │ │ AM16+ & AM5+) │ │ │ │ via Aux) │ │ MPPT) │ └─────────────────┘ └─────────────┘ └─────────────┘ └─────────────┘I’ll continue collecting more data and will share detailed graphs soon.

Knyee Energy ES-LV-16 Update Real World Testing Progress Hi all,Here’s a progress update on the Knyee ES-LV-16 after several weeks of continuous operation in my micro-grid. Efficiency & Temperature Behaviour Round trip efficiency is measuring consistently around 98%. I have also been charging and discharging the battery at a constant 6 kW. During these sustained high-power sessions the battery shows only a very small temperature rise above ambient. Ambient temperatures over the test period have ranged from -2°C to 22°C, and the pack continues to run impressively cool. BMS Communication & Flexibility I have switched the battery between different inverters and the BMS communication happens seamlessly every time after selecting the correct protocol in the Knyee App. It also performs very well in pure voltage mode. Capacity & Cell Quality Although the design capacity is listed as 16.08 kWh, I am consistently able to extract close to 17.6 kWh from the battery. This is a strong indicator of high-grade, new cells. Nominal capacity is calculated at 51.2V × 314Ah = 16.08 kWh. Delivering close to 17.6 kWh means the cells are actually producing significantly more than their rated 314Ah roughly in the 340Ah+ range. New, high-quality Grade-A LiFePO4 cells often show this kind of over capacity when fresh. Lower-grade or aged cells rarely deliver this much above the rated figure. BMS App The Knyee App remains one of the strongest points of this battery. It is extremely comprehensive and offers a high level of visibility and control. Key features I am making use of include: Detailed real-time cell-level data (individual cell voltages, multiple temperature sensors, balancing status) Clear historical logs and graphs Easy protocol selection for different inverter brands Comprehensive alarm and protection event logs Parameter monitoring Reliable remote access over WiFi I am still figuring out the best way to export the data from the app so I can analyse it properly on my computer. I will post screenshots of the app and detailed charge/discharge curves at a later stage once I have sorted the data export. Ongoing Testing I will continue both short term and long term evaluation, including further capacity verification, higher load testing, extended cycling, and long term capacity retention monitoring. More detailed updates will follow as the data builds up. Happy to answer any questions. Cheers!
