solasola: Good one. But if you will have to run power socket points on DC, especially from room to room, the drop in DC voltage that occur over long distances will preclude that. You will also require thick gauge wires for those long distance connections if DC appliances that it will handle are more than ordinary DC lights, eg A 30watts led TV some 15 meters away from the power source will require some thick gauge wires, same for an 80 watts refrigerator. You will also need to ensure the voltage of your DC power thru the wires is higher than the nominal voltage of your appliances and then use a DC-DC buck to get the desired voltage at the point of termination to each outlet. For instance, what I do is have btw 16v-24v running from to the charging ports around the house and then USB wall sockets (12v-24v input range) buck convert to 5v output. Light supplies of 16-24v get supplied to CC-CV buck packs that supply 12v to light bulbs for other appliances (cctvs, alarm systems, sprinklers etc). DC, though desirable for efficiency is not as good as AC for very long distances. 3 Likes |

An urgent advice is needed please,Can i buy a solar panel and charging comtroller plus deep circle battery and use my ups as an inverter itself? |

harizonal123: I contacted the seller and he gave me same advise: split the wires in two like Y and connect. Thanks all. |

Ejiyke24: I read something like that on YouTube. The man replaced the follow come 9ah12v battery with a 40ah 12v battery and used it to power his appliances, even a drill. Will send the link shortly if I still get it. 1 Like |

Please, I need advice. I want to buy Prag 2.5kva 24v inverter with 2 batteries. Please, What size of solar panel will fit in and also a matching mppt charge controller? |

Donsco: Like the gurus will say, define your load first. |
Re: Solar Energy, A Complement To FTA by Donsco(m): 6:04pm On Sep 29, 2019 |
Topmost11: 300 watts continuous load, and an inverter refrigerator which won't be on always. Will pump water during the day. Thank you. |

Ejiyke24:Yes of course, I use a similar setup myself |

zeestone99: This is awesome. Does it have inverter compatibility issue? I mean, can one use it with any 48v set up? |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 7:59pm On Sep 29, 2019 |
Ejiyke24: yeah, you can.. the major challnge the ups has is the small battery and the small charging current, since you intend to bypass these short comings by using a bigger battery...and solar panels to charge the battery...then you should be fine.. the only gray area is longevity os such a setup...you know a ups is not designed for sustained inverter load carrying, max most ups can do is 1hr on battery, what am not sure of is how the electronics will behave under sustained load...when used as an inverter.............does it have a cooling fan?? you can set aside 10k or 15k and buy a cheap 800va or 1kva inverter...souer has such products plenty..check konga or jumia, or the inhouse vendors 3 Likes |

Donsco: From advise given me when I asked same question, you will need at least 1500watts(combined) panel, and a cc of not less than 40a. In my case I opted for a 60a cc to allow for possible future upgrade. I just got supplied a cc via aliexpress that cost about 30k. Gurus in the house will finetune my message for you. Like someone will always post, I am a novice o. 1 Like 1 Share |
Re: Solar Energy, A Complement To FTA by Topmost11(m): 9:56pm On Sep 29, 2019 |
House, happy Sunday. I saw my pwm cc push up to 19a today. Will that not be too high a charge current for a single 200ah battery? What is the max charging current of batteries? It usually fluctuates between 4.5 and 10. But I happened to check today and noticed that it went as high as that. 4 panels of 150 watts should have constant 32a ie(8a×4) at least is what I am told. |

Dishtech: I didn't know this Lifepo4 batteries can be connected in series. I know this battery is rated 5a 14.6v but how come you use 40a Charge controller. Abeg abi novice o. Wanna understand. |
Re: Solar Energy, A Complement To FTA by Dishtech(m): 12:12pm On Sep 30, 2019 |
Donsco:My panel is just 250watts only so can not deliver up to 40a, is just an oversized. |

ceaser:I hail thee. You quite grounded on this. Well I have already put all you said into consideration. I have learned so much in practice. 9 months counting and its working perfectly for me. I am looking to increasing my battery capacity and solar panels. DC wiring has made live wonderful for me. I just wasn't ready to spend so much on inverter, battery etal. The DC journey has been rewarding so far. |

Pls advice urgently needed on the setup in the picture. Panel is 600watts Wiring is parallel Inverter is 12v, 900vac Thanks

Good morning everyone, I would like to buy Prag 4kva 24v inverter with 2 units of 200ah batteries. Continuous load will be about 350watts but wants to accommodate water pump and ironing (low voltage), please what size of solar panel and mppt charge controller should I budget and hope for in order to achieve good efficiency of the system? |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 12:02pm On Oct 01, 2019 |
Donsco: your plan is doomed from the start, make effort to read previous pages, this issue has been discussed a thousand times. max load u shud put on a 12v 200ah battery is c/20 wch is 10amps which is equal to 120w, since u hv 2 of them, then its 240w...u may not do serious harm to the bank if u intermittently draw x2 of this say 480w for short periods ie c/10, but anything higher than this...spells premature death for the battery. google well, to gain more knowledge about what you are about to enter into 1 Like |

Re: Solar Energy, A Complement To FTA by earthrealm(m): 7:02pm On Oct 01, 2019 |
dragnet: that has an inherent problem, and would need expert supervision to make sure damage doesnt occur. am thinking along the lines of overcharging the batts..., assuming his pumping machine is 1.5hp..ie 1200w approx, he would need panels of that wattage to scale by, factoring in losses and all. say he has a 1500w array, at 24v, thats about 55amps or so...though average wud be 30a to 45amps, i averaged same when i had 1500w on a 24v inverter. let him steer clear of flooded batts, as they dont like such high currents, as i dont think it would be possible for him to always be available, monitoring the harvest, so as to go switch on his heavy loads, when harvest is high... |
