hello Niyi, please for a 48v system, how many Hao2 will I need for 3 strings and for 2 strings? Thanks |
Re: Solar Energy, A Complement To FTA by JUO(m): 9:53am On May 28, 2018 |
solibayo:If you had bought the items yourself the system will still fail in 6months. why your load is extremely outrageous for 2 units of 200ah and 900w solar (label). for you to adequately/average enjoy solar you need the minimum of 4 units of 200ah and 2.5kw array, a good 1.5-2.5kva inverter can serve, 60a mppt. All hope is not lost you can still rescue the situation. Good luck 6 Likes |

I am assuming you have 12v batteries? If so then each 48v string should have 1 unit of HA02 dedicated to it so for 3 48v strings you would use 3 units of the HA02. If you are creative you can actually use 1 unit HA02 and parallel it across the 3 48v strings - the unit would be working hard if your batteries are highly mismatched but not a problem if your batteries are new or closely matched in voltage. mcTrinity: 2 Likes |

Has anyone had a successful RMA transaction for SMA equipment with SMA? We have 3 SMA mini central 1100tl inverters being fed by 33kwp solar panels - 11kwp per inverter. There is also a cluster box and 3 sma SI 8.0H inverters. We have been having riso fault on 2 of the smc 1100 inverters and they refuse to lock. We have checked pc cables, connections etc. However, when we swap out the other two pv strings to the working inverter, there is no riso error again and the system works. It appears there is a problem with the smc inverters. Complete System is about 2 years old and powers a hospital. We reached out to Solarshop -where we bought the inverters and send an email as requested. Not even an acknowledgement email after a reminder. SMA was better -SMA france has been handling the case and we have gotten an RMA - However, we have to send the bad equipment to Germany, then they will send the replacement to our freight forwarder in France. For two inverters, we are finding it may cost us almost 800k shipping fees to send the 2 inverters and get back replacements. Does anybody have any ideas to reduce this cost or have a reliable freight forwarder in France Has any had a similar riso error on SMA inverters. |

so popped into villa to check up on my old folks solar setup. i am beginning to believe that the desulphator -powerpulse , is working its a 24v setup with 4 x 12v x 200ah mecury flooded battery. all 4 batteries were between 12.56v and 12.58v, 25.1V ON THE CC ,which was a bit unsettling, and i said it might be a fluke, so i loaded up a 250w,[fridge+lights] and the batteries dropped to btw 12.33v and 12.35v, 24.6v on the CC EVEN THOUGH THE batteries appear to be balanced, i strongly believe they are not so healthy, cos how can a mere 250w load drop the voltage from 25.1v to 24.6v in a 12v x 4 x 220ah fla batt bank. or is this a norml behaviour with fla batts? aborted my plans of hooking up the ha01 to the bank, lemme observe it some more. note: the powerpulse desulphator has been hooked up for about 12months now, and the series parallel connection of the batts was properly done with busbar, and equal cable lengths see the desulphator below, fab reviews, if reviews are anything to go by, am using the 24v model. https://www.amazon.com/Pulsetech-PowerPulse-12-Volt-Battery-Maintenance/dp/B004I6QREK/ref=sr_1_2?ie=UTF8&qid=1527582196&sr=8-2&keywords=power+pulse+desulfator |

From what you've stated above, the company fullfilled its warranty policy. The only cause I suspect as the fault is "thunder strike or heavy voltage surge/spike".

pranil: It's one more to admire the design of Victron mppt blue solar chargers. Last weekend while carrying out some scheduled maintenance on my battery bank (repositioning them, cleaning the terminal connections etc) as usual I turned off the battery fuse to the inverter and controllers (this was around 11-12am about the pick time of solar irradiance in Abuja) it was a complete rocky mistake but little did I know as I took my time in making sure bolts where retight, cleaned terminal washers and changed battery positions. When I was done in about an hour and half later. I noticed the charge controllers were both on float.. At least I wondered why.. Then I remembered that I had disconnected the battery while the PV was still connected. Rather than see blue smoke the mppt solar from victron which are designed to have their circuit powered from solar as well as battery simply interpreted the lack of a battery load to mean a full battery state of charge moved to the part of the PV IV curve where zero power is generated essentially safely shutting down the controller while the pv remains in open circuit voltage with zero current passing through. Had I been using another controller.. I would have been here receiving sorry for my rocky error. Instead I connected the battery back and got the system working like before. Like Pranil noted a while back. How a cc is designed matters a lot. 5 Likes |

bigrovar: Insufficient data. I've made the same mistake with Midnite Classic CC and deliberately tried again twice. The iTracer I use for backup has survived the same on numerous occasions (intentional and unintentional) while I was learning my ropes; Xantrex had no issue either. Seen abunafiu survive a similar situation with his MorningStar Tristar 150. As the article Pranil posted states, running at full power might have something to do with it. My understanding of the issue is that most MPPT CC have some tolerance built in for these disconnections. The problem might have to with the amount of power (my Midnite was at full power around 1pm yet stayed alive; my own heart nearly gave out as I thought that was the end). 2 Likes |

@house, whenever I top up my fla batts with distilled water, and I look inside, the whole electrolyte appears very cloudy or dirty, and then clears up after a while. it appears I have lots of sediments at the bottom, is this a cause for alarm, should I drain the electrolyte and refill with fresh one? |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 7:37am On May 30, 2018 |
Similar stories for the MorningStar MPPT 60 - I had disconnected PV at around 2000watts several times without issues. The one accidental breaker trip when connected to a 4.5kw array at full sun (CC was passing the max 60amps into battery) blew the CC instantly. MorningStar have released a firmware update that includes 'enhanced protection for battery disconnected while PV still connected'. Although I have the above firmware update installed for my two CC's and nearly all clients, I have not the courage to attempt an experiment such as you have done to deliberately test to see if the CC would blow For me I only use manual disconnects (not MCB) with a lock down feature between CC and battery - you will need to unscrew a clamp before you can gain access to disconnect the CC from battery, hopefully in the 2 minutes or so it takes to perform the disconnect, alarm bells would have gone off in my head to ensure CC is disconnected from PV array first and so far so good it has been working flawlessly Saipro: 2 Likes |

No please! Do not drain electrolyte except you notice a catastrophic decline in performance that equalization e.t.c cannot fix. Sediments are a natural part of battery charge and discharge as the active plate material erodes away (battery charging/discharging & discharging is actually really a corrosive/destructive electro-chemical process) and most quality batteries have a substantial sediment trap at the bottom to ensure the broken off sediments are contained and do not short out the battery. More especially, actually replacing electrolyte (not talking about topping off with distilled water here o) is a very stressful process and certainly not for the faint of heart. Reprobate: 5 Likes |
