dapsyra: Yeah i know that...just trying to simplify it for him 300w poly and 300w mono....same brand will have major differences/variation in Vmp. While 300w of most common brands will have close/similar Vmp. I hv mixed renogy usa, myhome, sunfit mono panels..no shaking cos their Vmp was quite close 1 Like |

earthrealm: Thanks so much , the reason i asked was bcus i won't be able to buy all the panels i need at a go, so i would probably buy them at different time In case i buy the first set and i latter want to add to iit and the fornal brand i buy is probably not in the market, so i wanted to know if i can add a different brand to the set up Thank you ojeysky:and dapsyra: |

adrusa: I will be interested in doing this as well, as I have been relying on timer sockets for some of my appliances. If you don't mind, can you explain how to get just one appliance set-up for such management? I am more interested in the electrical part; how it interface with your home circuit and the software part. |

essegis: Good, this is where the work dey. I hope u can disconnect them from the present 24p and reconnect them in 1p4s? If yes, you will do this 24 times! Ie each set of 4 in series. This is the best way to identify a bad cell and remove it. Just put a light load on each set up. And monitor the voltage of each cell, it is a task of patience as I've said before. You may not be able to identify the bad cells if u ve 24 in parallel. In fact, the bad ones in the parallel mix will eventually destroy the good ones. Pls, disconnect them asap! 1 Like |

Hello house of solar I have a 12V 105AH Pb acid (VR) battery whose spec sheet indicates the 1. Charging Method for cycle use as: Control voltage: 14.4V to 14.9V Initial current: 42.0A or smaller 2. Cut off voltage: Cut off voltage/Discharge current: 10.5V/5.25A-21.0A 10.2V/21.0A-52.5A 9.9V/52.5A-105A 9.3V/105A-210A These values make it seem it's safe to run down to it and nothing will happen except cycle life but ... I have a 24V hybrid inverter whose maximum low DC cut off voltage is 24V. My inquiries with its appreciated response are What voltage is recommended for: Bulk charge, float charge, equalization voltage. What is the specified time for equalization of Pb acid battery and how long in between equalization (in days) As per the low DC cut off voltage, 50% DoD is about 24.12V while 30% is 24.6V (from charts I have seen online and here) but the inverter has just 24V. Is there a digital device I can install in between the inverter and battery to disconnect supply to inverter at my set DoD. Also on LFP batteries, between the cylindrical and prismatic type, which is more preferable |

Men in the house. I'm planning on upgrading from lead acid to lithium so i need expert review on this battery. Is it a good buy �? Will i regret on the long run? Can a hybrid luminous inverter charge it effectively? thanks for your anticipated response

Re: Solar Energy, A Complement To FTA by litaninja(m): 9:50am On Jul 01, 2020 |
Yea, i'm hoping to do same. Nothing too fancy to start with. e.g. - Having an esp based switch trigger during daylight hours when solar generation is within a certain threshold (from inverter monitoring) and cutting off either below a certain threshold (e.g. cloudy cover for a length of time ) or at sundown - Checking on 2 or 3 esp based switches for current state when grid power fails and change state based on priority set. e,g, if 2 ACs are running -> grid power fails, switch the lower priority one off. Stuff like that. adrusa: |

ojeysky: Alternatively, if you have raspberry pi you can get ICC software from info@iccsoftware.co.za at a fee. Afterwards, I can give you a seller on aliexpress that tasmotizes Esp-based devices or you can get some of the device (eg Sonoff) yourself and flash with tasmota. ICC software will use any of the inverter parameter you want to automate your device on and off. |

futurenix: Let's just say it's one of the disadvantages we get for not going premium, I guess we should just leave with that I set mine to the 24v cut-off but I endeavour not to get to that level in the first place because mine is LFP, I think with lead acid you should be fine with 24v. On the LFP question, both are fine though I prefer the prismatic as I get to work with fewer cells but it's a matter of preference not performance |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 1:34pm On Jul 01, 2020 |
olatade: Someone gave a review of this felicity LFP and it didn't sound interesting.... So I will advice you don't expect too much from it. You can't charge an LFP effectively with that inverter, you need something with adjustable voltage |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 1:36pm On Jul 01, 2020 |
kiekie1: Battery and inverter for that price or was it a typo? |

I have 24V inverter now. Is it possible to charge two batteries in series with 24V2.5KVA without issue? They are new batteries. I want to charge before installation |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 4:34pm On Jul 01, 2020 |
The general thinking is that the Cylindrical cells are better as they dissipate heat more efficiently than prismatic cells. Being that they are tightly wound in a metal casing, they are also less susceptible to degradation from thermal cycling as they charge and discharge as well as mechanical stress and vibrations when/if moved around. ojeysky: 1 Like |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 4:36pm On Jul 01, 2020 |
ojtech8291: yeah, you can do this.. however the correct textbook procedure is to use a standalone 12v batt charger and charge each battery to full, before hooking them up to the inverter, this would ensure the batts are balanced from day 1. many people dont do this......i dont do it too if you have batt balancers installed in the setup, you should be fine, either way |
