toyeoye:this quote is not good atall. your installer is not in touch with present realities.. with an improved budget, u should be doing a 48v system. u need a good 48v hybrid inverter, 48v 230ah or 280ah real capacity lithium battery and atleast 8pcs or 10pcs of 450w panels. 1 Like

Good morning guys. Is anyone here using a Victron smartshunt? I need to know if it can be connected to an inverter to provide the inverter with details such as temps and an accurate SOC for the connected battery If it can, then I'll be looking to buy one so please let me know if you have for sale too |

NiyiOmoIyunade has already said it in a more simpler term, from the cable sizing to choice of inverter, charge controller and a few other things require that the system be reviewed. Probably the inverter was randomly oversized, with knowledge learnt here so far, i think it is comprehensible to help try a DIY audit by noting nameplate of appliances to be used and if these seems out of your deep you can try the link in my signature, it might be of help to you. toyeoye: |

First the smarshunt allows info to be transmitted via cable "V.E Direct" and also bluetooth The alternate integration different from its native use is via Econcms used on rasberry pi and Hybrid Axpert variant inverters, my knowledge of its use is limited but i believe you can get it to do lots more anyways, especially the SoC based on certain set parameters. In case you get to solve this before i do based on info above, kindly reach out to get a hold of the smartshunt MontyNG: |

If you use an all Victron system, your smart shunt will communicate with the system data aggregator aka GX device. Inverters, MPPTs, battery monitors e.t.c all communicate with this GX device which also doubles as the single point of control. If your inverter is non Victron, then you will need an interfacer that will capture smart shunt data and pass it on to the inverter (assumes some smarts embedded in the inverter). The smart shunt runs comms through VeDirect and your interfacer can be NodeRed, EmonCMS, HA, OpenHab or custom script running on a Raspberry Pi or a microcontroller mounted on a development board e.g Arduino or ESP32. I tend to prefer own roll custom scripts as it forces you to learn the backend of how things work and allows you to do a lot more. There is a possibility to use the smartshunt data broadcast over bluetooth but there is very limited support for this due to the peculiar issues with bluetooth comms. MontyNG: 3 Likes |

I forgot to add that if you get a RaspBerry Pi and install the Victron Venus OS large image on it you can simply connect a VeDirect to USB cable between your smart shunt and the RaspBerry Pi and you are good to go. The data from the smart shunt will now be available via LAN and across the internet (VRM portal) - a cheap RaspBerry Pi now becomes your GX device. The Victron Venus OS large image also comes already bundled with node red which is a good way to get into building logic flows and automation. NiyiOmoIyunade: 1 Like |

Hi Solar Gurus, pls I need help!!! I plan to setup a solar power system comprising of 200ah lead acid battery (monbat) 1KVA - 1.5KVA inverter. What value of MPPT charge controller and solar panels do I need for this system? I have a load of 450 watts and I intend to be running it while charging the battery too in about 6 hours of sunlight. |

Penuelseun:Lithium battery does not have settings for absorption and float, it just one setting, if it is pwm set both settings the same but most mppt has direct setting for lithium battery |
Re: Solar Energy, A Complement To FTA by Penuelseun(m): 7:35am On Sep 28, 2022 |
Dishtech:Oga lithium battery has two charge settings, bulk which is CC-CV and float which comes up when your battery is fully charged. Leaving your lithium battery in a high state of charge always is detrimental to the health of your battery in the long run |
Re: Solar Energy, A Complement To FTA by MontyNG(m): 11:28am On Sep 28, 2022 |
Wow! Thanks a lot Niyi. No it's not an all victron setup. I'm using a deye/sunsynk 5kw inverter and batteries that only have Bluetooth comms. This limits me in terms of an ideal inverter config since there's no accurate soc value for the inverter to use, and using just voltages is not ideal So I'll have the wifi module connected in the rs232 port on the inverter.. That will allow me to use the inverter's own wifi app but these are usually limited. On the rs485 port, I want to connect a pi running solar assistant. I'll now have a free CAN port and another rs485 port (meant for battery comms) So wouldn't be able to implement this solution with another pi as a gx device unless I sacrifice solar assistant.

Re: Solar Energy, A Complement To FTA by MontyNG(m): 11:32am On Sep 28, 2022 |
I'm exploring the Juntek shunt now. This has an rs485 data port. Trying to see if this port can be used to feed data to the inverter but haven't found the required info yet |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 12:21pm On Sep 28, 2022 |
Things are now far easier boss. If you put the Victron Venus OS large image on a Raspberry Pi (be sure to use a 3B and not a Pi4) - you can natively connect your Victron smart shunt via VeDirect to USB, also your BMS can natively use the Venus OS driver for serial batteries so that SoC and cell level info are plug and play available on the Pi - works if your BMS is Daly or JBD or Jk and a host of others. So already you have shunt and BMS data available on the VeBus network and available to use for info and control. The Venus OS large image has NodeRed and you can create flows to pass BMS SoC data from the USB port of the Pi to the RS485 or CAN port of your Deye - if you are using CAN for control (charging etc) then you must have some control parameters setup. For free Victron already provided you all the tools you need to attack most automation projects both on Victron and non Victron equipment ![]() ![]() ![]() MontyNG: 1 Like |

Mehn... *mind blown* Thanks boss. Let me start arranging to get all the parts. I'll be intouch again when I need to combine it all - to create the flows to pass on to the inverter CAN port. It's that one that I still don't fully get but might all click into place once I start assembling Really appreciate it! Thanks NiyiOmoIyunade: |

Re: Solar Energy, A Complement To FTA by zeestone99(m): 9:20pm On Sep 28, 2022 |
toyeoye: There might be a reason why your installer is going the 24v route. 24v systems are less prone to battery failure than the 48v. You will need to compensate for that by installing higher amperage mppt controllers. In most cases two units or more depending on how large the system is. Just go back and do your assignment on the panels and controller size. 1 Like |

Pls does anybody know of a very good brand of chest or upright freezer? A popular local brand I got few years ago just packed up. I decided to visit their showroom to get a replacement but to my astonishment, I discovered they are now selling generic China made products rebranded with their own brand name. They obviously decided to throw their reputation and quality to the gutter for monetary gains. 1 Like |
