Juror: End user actually, not in the business. The Powmr MPPT 60 beats the Homaya M1000, I think I made that clear. I just wanted to make it clear that it is dangerous to attempt to run it at its limit when the manufacturer itself says so. I also made the point that if running it at 160V PV will kill it, it is unfair that they have not told us the safe maximum PV. That any potential user needs to have that information before deciding and along the way it breaks |

mctfopt: Something similar has been said about Felicity, don't run it at PV max, it will throw an error It was thanks to this thread |

How do solar users survive this season of rains |

dacool1: This is how I try 1. Reduce Energy Usage 2. Performance Monitoring 3. Use gen as backup to charge batteries as last resort |

Please can someone recommend a good 2.5kva inverter for me --budget. 250k Also a good tabular battery budget 170k. Lastly please is it possible to use a 2.5kva 24v with 1 220ah battery?. Thanks |
Re: Solar Energy, A Complement To FTA by fatherbeeman: 10:21am On Jun 11, 2023 |
Please any one with 2.5kva yohako review.. thanks |
Re: Solar Energy, A Complement To FTA by Hybrid600: 11:31am On Jun 11, 2023 |
You can't use 1 unit of 220ah battery on a 2.5kva 24v system. It must be at least 2units of batteries. fatherbeeman: |

toyeoye: In addition to the above, over privisioning helps (in plain english more solar panels than your actual consumption, a larger array will generate more than a smaller array in difficult weather) and efficient equipment (MPPT instead of PWM) 3 Likes |
Re: Solar Energy, A Complement To FTA by isangjohnson: 12:56pm On Jun 11, 2023 |
toyeoye:Generator as backup for #550/litre is irritating. If there is small cash and his battery is lead acid, then let him add pv and manage his loads. If his battery is lifepo4, then let him manage his loads with partial charging of the battery. Economic aspect of renewable energy is the key for middle/third class citizens. |
Re: Solar Energy, A Complement To FTA by aviona: 1:23pm On Jun 11, 2023 |
You've just hit the nail on the head @ Fegeitok. With a reasonable PV oversizing you are covered, so long as you remain under your charger's max Voc. Also, a larger battery bank helps make up for bad weather. Some people even maintain two separate arrays and banks, and just switch between them at different times of the day. Decently oversized PV arrays alongside a good MPPT charger, require minimal daylight (not even 🌞 sunlight), to go from bulk to floating, even with some loads on a rainy day. In summary, your PV and battery capacities can keep you "dry" even on a rainy day. Honestly, I haven't used a generator for years. |

Can 3.5kva and 2 220ah battery power a 1.5hpower submersible pump? |

brightk: https://www.youtube.com/watch?v=h4iOs2taeZM The over provisioning or oversizing begins with solar panels ( in technical speak PVs which is short for photo voltaic cells) This video should help 1 Like |

Straight answer... No osayuwamwen: |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 9:05pm On Jun 11, 2023 |
osayuwamwen: Instead use the 3.5kva with maybe 160ah 24v or 48v lifepo4 |
Re: Solar Energy, A Complement To FTA by oloet: 9:26pm On Jun 11, 2023 |

It couldn't b yes if 1. If ur battery is lifepo4 of 3kwh up 2. If ur panel is 4kw up n u can pump wen the sun is up, even wen d sun goes down ur panel should still generate up to 1.6-2kw while the remaining 700/300w will taken from ur lead acid batteries. And most importantly, ur 3.5kva inverter must b those variant with toroidal transformer, they handle surge better, if ure using a high frequency inverter, don't pump oloet: |
Re: Solar Energy, A Complement To FTA by adrusa: 8:39am On Jun 12, 2023 |
ojeysky: Irrespective of the amount of battery you have, a 1.5hp submersible pump will shut down your 3.5Kva inverter. I dare anyone to try this and report back to the house. I have tried with a 3KW HF inverter before and it promptly shuts down. The pump initial power surge can get to almost 5kW. A good transformer (LF) based inverter may try, but I will like to see a report. 3 Likes |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 10:17am On Jun 12, 2023 |
adrusa: Typically a good 3.5kva inverter should be able to accommodate 2x surge, if that is not the case then that inverter isn't good enough. I am also not sure a 1.5hp pump surge should get up to 5kw....I have a feeling yours probably tripped because of battery lvd |
