Give growatt a shot IMO IYGEAL: Battery is a standalone 24V, inverter is also 24v.
Tried feeding PV and also experienced a spark. Took it back to the repair guys to try their luck.
So I'm on the look out for a 24V 3 to 3.5kva hybrid inverter which would preferably have a lithium profile.
I need opinions on which is better between Growat, iCellpower and Sorotec. I think my preference would be the one with less idle power consumption and less minimum pv input voltage. |

Yes. Rated to your needs IYGEAL: Do you mean circuit breakers? |

What I have learnt is if the arc is too much something isn't right. And from your explaination below, I guess you don't have a battery disconnect too Just for the sake of when you have it fixed and returned, please kindly get them Disconnectors as to proceed with ease and enjoy your system IYGEAL: That may be possible but very unlikely. The sound was reminiscent of a capacitor forced to discharge.
What the inverter does now is produce a massive spark on trying to connect it to the battery. Sometimes it shorts off the battery. The sparks are big enough that they almost washed off the threads of the battery terminal. |

Yes I can it but "never" Efficiently because you need like 600W for every 200Ah of battery and considering you want to use 4 batteries 600W x 4 = 2400W ideally But in reality you might want to over size not more than 150% if using Tier one or 200% of charge controller if using tier 2. All the above depends on your pocket, grid availability, and last aim of use etc. Checked throught your recent post, if you have not bought that inverter I will recommend Growatt for you can handle over sizing too and sure will charge your battery with no stress. abbeymighty: Please can 600w.

Sorry about your inverter going bad but the scenario you explain feels rather weird to me. The PV wasn't say energized like when the sun was up ....so power wasn't suppose to be coming in. I have been to site with no PV disconnect for conventional charge controller and disconnecting the PV while operating " though bad" never had a fireback or otherwise . My educative guess is that the PV input and BATTERY might have a kinda common bus .... So maybe on removing the cable some tiny strands bridge the +ve and -ve. Just my opinion. ..... IYGEAL: The silent y before s is probably also physically silent 
I was going to make these adjustments but it looks like I have carelessly fried my new hybrid pet.
So I was going to shorten the PV cable last night but forgot to switch off the inverter. Breakers I ordered are yet to arrive so there is no breaker between the inverter and PV. There was a loud sparkling noise the moment I put a screw driver to unscrew the PV.
Sent it to repairs but I'm guessing the board is gone and I might be on the look out for a new 3.5kva hybrid. |

I believe there are Engineer and there are engineers As a basic knowledge potential difference - P.D potential flows from higher to lower P.D For a PWM that works on pulse modulation, something slightly above the Battery voltage is considered the sweet spot. E.g 18V for 12V 30V for 24V 50+ for 48V Anything out of the above equals a system that is inefficient and poorly designed. solasola: I have seen lots of discussion on pv setups, 2S2P,6S2P....... I think such setups cant work for Pwm cc and simple inverters with either 12v/24v operational voltage. I am asking this because i have come across a system like that the client said failed. I noticed pv was reading about 56v for a 24v inverter. Going up, is saw that 3pc of 100w were connected in series pv wires were corroded with whitish powder, cc was bad, batteries were overheating too and one was melting sef.
The client had to rewire the pv wire since they were badly damaged, buy new cc, change batteries, opt for a 12v system, and has enjoyed his system since then. |

Chuckle! Their is a term called "jo mor" in yoruba or weld it as an English translation. It's a loose term to create solution on the fly. My team and I have being to this site during the summer and the sun rise and sun site is quite a bizzare one, our decision was to harvest much of light sun that the summer has to offer. Kindly find below our digital compass that clearly showed the sun path in July 2020 And December 2020 respectively. Then maybe you can understand our POV NiyiOmoIyunade: Hmmmmmm
I was not aware any advantage could be gained by a NE installation when the location is on the equator.
I do South, then West then East in that order of preference. I will do more research to understand what you have done.

Nice observation We decided to use the other part of the roof because the geo-location of the factory is in such a way that the tilt of the sun in harmattan glides to the other side while during the rainy season it's on the installed side of the roof where it pass over the panel from morning to evening. Considering cloudy days, rainy days, over cast and other associated things in relation to irradiance, we consider a 5° tilt gain factored in to compensate. ojesymsym: Using the East facing DSTV dish as reference, I am wondering why you choose to use the NE direction for your solar installation when it seems the Southern part of the roof was available? |

Thanks for the enlightenment. NiyiOmoIyunade: Yes all DC sources for charge and discharge connected at only one point but not like the diagram you drew.
You want currents moving in and out of battery to pass through exactly thesame number of hoops.
Once your connections are becoming numerous best to use a busbar. One can easily DIY a busbar from a suitably thick earth bar drilled and cut to spec then mounted in an electrical box. At max currents in the system you want busbar to stay cool at best or slightly warm at worst. |
Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 9:16pm On Jan 27, 2021 |
Yes, they will be more balanced. Considering that equal cable lengths are used to terminate battery terminals on the busbar. Sharing the panels on PWM Cc and the Inbuilt is more preferable considering that MPPT is the inbuilt CC CREATING a system of busbar will lead to little or insignificant loss in the system, since all source are constant to a single location. In my best opinion saint2ace: Quick question, will the introduction of a busbar make this system more balanced and efficient? Scenerio being a split in panels to 2pv array if 2s2p each, one connected to the own charger controller, and the second connected to the hybrid inverter to achieve more PV gains since CC is pwm on both external and hybrid (spec sheet should clarify).
Secondly, creating 2 banks of 2s1p and connecting to the busbar.
Lastly, all connections terminatiing on the busbar, drawing feed from the busbar too.
As stated above will this create a more balanced and efficient system, or there will be too much power loss.
I await responses |
Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 9:11pm On Jan 27, 2021 |
If i understand you better, use only one positive and negative for all connections I.e. inverter and charge controller? NiyiOmoIyunade: I want to clarify that for battery connections, all DC utilities must connect to the same battery terminals. All charging sources (grid, gen and solar) and all loads must connect to thesame terminals.
One may use a busbar to allow multiple DC utilities connect to the same battery terminal.

It is very feasible, I noticed 2s or 3s both works just fine It's not just about maximizing the upper input voltage range of a charge controller but working within the MPPT range of the charge controller No, they are not 500W panels That's what the engineering dictates for the installation. I guess you have a contrary opinion? ceaser: 2s2p configuration panel for 48v system? How feasible is that? Or are the panels 500 watts each? |
Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 6:58am On Jan 23, 2021 |
No, it is a 2s2p configuration ceaser: Is that 4s3p config for the 48v system? |

I understand better now, makes sense ojeysky: I used the lowest voltage and maximum current to determine the maximum power that the device will consume. So depending on the TV settings at 100v it could require up to 2.1A but the current will be lower at higher voltage. In naija case where we use 230v(220-240) even if all the TV features are utilized 100%, the current won't be up to 1A thereby keeping power within the 210w max |

Harmattan season is here again
Some installations might go under in coming months, while some with forward thinking owners or system managers sort for ways to prevent their investments depreciation.
Recent survey has it that "solar system loses about 30% of power production due to debris, bird poo, decaying leafs, and dust"
Be forward thinking today and request for a system check up and maintenance

Satellite TV Technology › Re: Solar Energy, A Complement To FTA by olopan(m): 8:52pm On Nov 29, 2020 |
That's about right for both scenarios stated, What I can't collaborate fully is the maximum power at lower voltage .... but according to power law .... It's plausible. ojeysky: For the first, operating range is wider hence I think the 2.1A is probably the maximum current at the least voltage of 100v which makes it 210w max
For the second 135w I expect is the maximum and 75w is the regular (typical).
