ab3458: first of all, let me say that every voltage system has its advantage and disadvantage... with 12V system, there's no issue of unbalanced voltage among batteries.. with 2 units of 150Ah batteries, you'll need to connect the two batteries in parallel @12V to give you a total of 300Ah battery bank. This means you need a 12V inverter that has a charging current of at least 30A. otherwise, in no distant time you'll be complaining that your batteries aren't sustaining again because sulfate has built some duplex on the plates with 24V inverter, you'll need at least 15A charging current. 12V inverter will have more conversion loss compared to 24V inverter. in summary, I'll PERSONALLY recommend at least a 1.5kva/24V inverter. Trust me, a 1kva inverter won't be the ideal inverter for your system. 1kva inverter is only about 800W. and don't worry about having unbalanced voltage with your 24v setup, as long as you don't frequently discharge your battery bank deeply. or better yet, you can install a battery balancer cheers 1 Like |

Does the SuKam Falcon have the ability to take the batteries to a proper absorb voltage between 14.1v to 14.8v per 12v battery? Spending a few hours in absorb after each deep discharge is critical to the batteries long term health and performance. Except the intended use is very light cycles (minimal discharge) mcTrinity: |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 1:00pm On Sep 13, 2018 |
Give the OP a brand that will charge his batteries properly na. I think Luminous has some potential with it's adjustable voltage setpoints (at least on the 3.5KvA) but I never got a chance to check the behaviour thoroughly. Getting to the battery manufacturer recommended absorb voltage after each deep discharge cycle and staying there for a few hours is critical to the long term health and performance of the battery. zeestone99: |

Not 3.5kVA bros.I mean any inverter within the size range he wants that has user selectable battery voltage settings. I was using the Luminous 3.5kVA as an example of such an indian design inverter that seemed capable of going above 14v per 12v battery for absorb (this capability as yet unverifed by me) zeestone99: |
Re: Solar Energy, A Complement To FTA by remizvxcq(m): 8:42pm On Sep 13, 2018 |
Thanks for welcoming me. I want to share a recent experience of using Outback Flexmax FM80 within the Victron ecosystem. Issue: Victron CCGX (using the Multiplus as the default battery monitor) is confused by solar charging of battery bank by a non-Victron charge controller. 10:00am PHCN is off. OFM80 is charging the battery bank. Even in bright sunlight, with the OFM80 charging the battery bank upwards, the CCGX is reporting depletion of the battery bank SOC%. CCGX reports correctly that battery voltage is changing in line with the reports of the OFM80 and the BMV712Smart, but the CCGX SOC % is not correct. 1:40am PHCN resumes, and Multiplus switches to Float. OFM80 and BMV712 and CCGX reports similar voltage. But CCGX continues to show depleting SOC% levels even with both solar charging and PHCN charging going into the inverter, and battery voltage is going up! 2:80pm Eventually, the MultiPlus is switched off and restarted. After a brief pause, the SOC jumps from 55% Bulk to 85% Absorption. Within next 10 minutes, it jumps from 86% Absorption to 100% Float. Recommendation 1. a Ve.Direct cable between the BMV712Smart and the CCGX that enables the BMV to be the reference battery monitor instead of the MultiPlus. 2. Alternatively, a contactor which stops and restarts the MultiPlus after a few minutes in order to enable the SOC algorithm within the MultiPlus to catch up. This would however mess with the UPS function of the MultiPlus, and adds complexity. current system: 3.18kWp Solar Array = 9x270w Trinasolar Mono & 3x250w Solarworld AG Poly; Victron Multiplus 5kVa; Outback Flexmax FM80; Quanta Amaron 200AH@48v; 7.5kVa Kipor diesel genset; Gas cooker; Energy efficient appliances; Passive cooling & heating of buildings. 2 Likes |

NiyiOmoIyunade: Having used the sukam falcon plus (first the 12v then 24v) for over a year. I can confirm that it is capable of absorption voltage at 28. 8v or 12.4v for 24 and 12v respectively. I had a watt/ voltage monitor attached permanently to the battery bank and I could see the battery voltage in the fly. I can also confirm that the current going into the battery is in line with stated specifications. 1 Like |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 4:24am On Sep 14, 2018 |
remizvxcq: I have the ccgx to be over rated. I had a chance to go with it when I was looking at logging and remote monitoring options. For the price it is nothing more than a portable victron connect. Logging real time logging and data collection and aggregation can only be gained if linked up with victron vrm service and the option for Internet connectivity are very very limited for the device. The biggest draw back is not being device agnostic. It is designed to integrate with victron product alone and would thus only work in victron ecosystem. It is for these reason that I settled to using a Pi and Emoncms for my logging and I have not regretted over 4 month down the line. 1 Like |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 6:10am On Sep 14, 2018 |
28.8v absorb for 24v nominal system and 14.4v absorb for 12v nominal system. This is good news for the OP then - for whatever reason, I have never observed a SuKam that went past 13.8v charging voltage but I have seen a Luminous and Sinergy get into 14.4v range. I may have to reopen the chapter on these Indian design inverters - it seems my very brief experience with them has misled me to underrate them - I recall Oga GeorgeD1 and Barezzi also once confirmed to me that their SuKams could withstand equalization above 15v per 12v battery yet the 1 unit I borrowed for testing once would go into overload and trip off at high DC voltages - this would be the 3.5kVA 48v Fusion series - perhaps the unit already had an internal fault because I know it conked off soon after. bigrovar: |

Re: Solar Energy, A Complement To FTA by bigrovar(m): 8:55am On Sep 14, 2018 |
NiyiOmoIyunade: This I can also confirm. If you note I use a floaded acid battery and as a result sometimes hit close to 32v during equalization. Not once did the sukam go off during equalisation charge it always held firm. The same can not be said of my current axpert 3ks inverter which trips off once voltage hit 30. Sukam especially the falcon plus model I tried are very reliable and stable. They have relatively low idle load watt usage (the 1.6kva 24v uses about 28w) They offer simple design but use quality internals. The down side of the simplicity is the lack of charge profile control and a relatively weak charge current especially if you are using them without solar. 3 Likes |

Re: Solar Energy, A Complement To FTA by pranil(m): 3:06pm On Sep 14, 2018 |
remizvxcq: a Ve direct cable is enough from BMV to CCGX . Also ensure that CCGX the battery monitor is selected as BMV and not multi. Multi uses only voltage and it's own current for SOC while BMV has an overview of entire battery. There is no need to use the multi as battery monitor . Also, make sure that BMV is correctely set ( including sync) refer this video https://www.youtube.com/watch?v=4ReljfO3k6M BMV is one of the best battery monitors out there 2 Likes |

bigrovar: I beg to differ There are few functionalities which cannot be easily replicated in a PI and emoncms without hours of progarmming and extra hardware. I will name some of them as an example . However it is true that it is designed for victron ecosystem ( victron products , Fronius inverters ocenvolt generators, The price refecltes the software development and maintainance /support cost and not necessarily hardware cost which is essentailly a raspberry pi with additional IO devices 1. Using to control ESS ( energy storage system) CCGX manages the battery SOC and export-import power - Battery over Cabnbus , Energy meters over RS485TTLUSB, Fronius over LAN and multi over Ve Bus - that is a complex set of protocols to develop and mainatin 2. Start and stop of generators based on Battery, Load, grid condition including conditions set as per the time of the day with a real-time clock . As you will know unless separately added and programmed A Raspi does not have real-time clock deriving it's time from the internet on everyboot . 3. additional inputs such as Tank level sensor, temp sensors ( on Venus GX), Additional isolated Inputs outputs all need development cost and money If you need these functionalities then there is no real alternative and CCGX is bang for the buck. for a simple off-grid systme with Lead acid battery and inverter, i agree it is an overkill But then unlike many companies, Victron does not prohibit you from making your own implementation w( using raspberry pi) and even opensourcing the source code 4 Likes |

Thanks for the feedback. I hope no-one noticed the wrong times reported in my post above. 2:80pm indeed, not. It was 10:00am, 1:40pm and 2:08pm. Anyways.... The bmv712smart does a very good job of keeping track of the battery bank voltage and SOC. It is only necessary in the current system because of the presence of the Outback Flexmax FM80. The rascal is the MultiPlus, which needs to be physically switched off anytime PHCN resumes, and then restarted, before its SOC% adjusts to the reality of solar charging by the OFM80. I suspect that this may be due to the settings. I do not presently have ESS or any of the virtual assistants engaged: Just OFM80 connected to DC in, PHCN or genset changeover to AC in, the critical house loads are on AC1 out, and the non-essential loads on AC2 out. The MultiPlus also does not assign any figures to the DC power display, although I have 3 computer DC fans and a 12v LED light connected directly to the busbars. Can anyone help resolve this? I can manually calculate the DC loads, but I would like to see it on the CCGX display. However, I do not presently have a Ve.Direct cable... I will be ordering some Victron and Fronius products shortly. If anyone else is interested, please let me know so that I can bulk-buy and pass on the savings.

Saipro: A Primo works well for 1- systems. Be aware of the 1:1 rule for sizing the battery bank. Awaiting a donor EV from which to harvest a Li-ion battery bank, at a more affordable price than buying Victron's.
