Renewable Energy Innovators Cameroon (REIc) is a social enterprise based in Cameroon. REIc’s mission is to improve the lives of those in off-grid communities by providing renewable energy. This goal aligns with th. . Sabongari is located in the fertile Mbaw plain of Nwa Subdivision in Donga Mantung, Northwest Region of Cameroon. The community has more than thirty villages all of the. . The Sabongari expansion pilot project demonstrates the self- sustaining viability of Microgrid deployment that will provide electricity to 1,200 small villages. This deployment prim. . The local team is led by Numfor Jude, the founder and CEO of REIc. Jude and his core team members have more than ten years of experience in the electrification of off-grid communit. . The project expands REIc’s electrification services in Sabongari community to reach 7,000 people. Phase I of the project electrifies five remote villages in the Sabongari comm. [pdf]
Renewable energies, particularly solar photovoltaic energy, are critical for expanding the population’s access to electricity in a sustainable basis. PV systems produce decarbonized and environmentally friendly electricity, which helps fight global warming. Cameroon has significant solar photovoltaic (PV) potential across its territory.
However, solar energy is not a panacea for Cameroon’s lack of access to high-quality energy. Solar panel output is highly dependent on the erratic nature of both solar radiation and ambient temperature, which frequently leads to an imbalance between supply and demand.
This research 18 aimed to conduct an extensive technical and economic evaluation to determine the best approach for hybrid photovoltaic/wind systems integrating various types of energy storage to provide electricity to three particular areas in Cameroon: Fotokol, Figuil, and Idabato.
Cameroon 21st December 2021 – Solarworx has expanded it’s pilot program for interconnecting Solar Home Systems to a DC Microgrid to Cameroon.
Cameroon device monitoring Solarworx Solar Home Systems “Solego 80/160” are equipped with GSM modems that allow monitoring on an hourly basis depending on the network coverage. The energy data provided during the last 30 days from Cameroon can be tracked on the dashboard below.
Power outages, load shedding, and voltage drops are common on the electrical grid, causing significant social and economic consequences for the population. In 2021, Cameroon’s power network experienced an average system interruption duration index (SAIDI) of 162.6 h and an average system interruption frequency index (SAIFI) of 41.8 2.

Select one or more USB cables and click connect: Plug the RS485 USB cable into the SolarAssistant monitoring device. Once you click "connect" on the configuration page, you should see each BMS show up as a battery pack as shown below. One pack will be shown for each JK BMS connected in step 2 above. How to connect a JK BMS to SolarAssistant.
When using the ports on the right, SolarAssistant will "listen in" on parallel communication going between the JK BMSs that are connected together. This is similar to how the official JK BMS software works. When using the port on the left, you need to configure the BMS to use the "000 - 4G-GPS" protocol using the official JK BMS software.
This guide is for the newer JK inverter BMS, also known as the JK PB BMS range. See our original JK BMS guide if you have their older original BMS. Use a Seplos RS485 BMS cable. If you are creating your own cable, note that RS485B on pin 1 and RS485A on pin 2.
Let SolarAssistant perform it's own state of charge (SoC) calculation by counting power flowing in and out of the battery. This is a good fallback option for anyone who can't get a real BMS reading. It's less accurate than a Victron BMS but much more accurate than the standard voltage based readings of an inverter.
When using the port on the left, you need to configure the BMS to use the "000 - 4G-GPS" protocol using the official JK BMS software. This is the protocol also used by the original JK BMS. On the SolarAssistant configuration page, select the "JK BMS" protocol as shown below. Select one or more USB cables and click connect:
Given that the Pace and JK bms has protocol information to work by , it is possible to concentrate the metrics in order to create a single virtual BMS communicating to the Sunsysnk . However , the Sunsunk will see a single but accurate aggregate of the SOC's , it will not display individual SOC's .

Pulling the data into Home Assistant through the UART port connected to an ESP32 chip running ESPHome. The ESP chip sends all the data from the bms over Wifi. I have a new JK BMS coming in the mail - planning to set that up the same way this weekend with ESPHome. This one however I can connect via bluetooth instead of having to hard wire it.

This ESP32 is monitoring the JK-BMS as is in the picture. (I'll mount it later) through bluetooth. Love ESP technology! Would you be able to say how you got the ESP32 working with your JMS into Home Assistant? I'd love to sort that out - have the parts here!
