Thanks. I did chat the guy up and the downside was that requirement of grid to boost back the BMS in case it trips. My current pack isn't like that and the manufacturer indicated that it can be connected in series.

Yup, though I think if high current from sunlight can't wake up the BMS then I don't see how utility will do that, unfortunately I am off-grid so can't test that out. What's the specs of your bank and price?

ceaser:
And not just that. Okay, assuming by some fluke other than Low Voltage Disconnect, the BMS trips off due to maybe something like High voltage protection or short circuit protection and this happens when the sun is high up in the sky, then your CC can get fried.

Those scenario here does not shut the battery down like in the low voltage disconnect.

We recently met this 65inch plasma at a site . Client says this TV set cost him real money some 4 years ago & he isn't willing to let go .. This isn't the 1st site we're experiencing this as most don't really know plasma tv are energy guzzlers .. We see some clients who don't believe in just changing a working electronic and that's partly a major challenge we do face sometimes in renewable energy quotes & installation. Later some will say 2 battery system didn't last long with just TV on .. It's well !!

Wow are you serious ? My Samsung fridge/freezer with dimensions 555*637*1445mm² doesn't consume upto 200w if I can remember!

Be likely getting it from the same supplier that I got those 12v LFPs from once his consignments come in March/April.

There is no major down side to using a Victron CC with a Magnum inverter. Both are excellent products with solid engineering and design behind them.

The only issue is that your integration can become very difficult e.g if you want to deploy a system monitoring or management solution - Victron GX products only support Victron equipment and a limited set of ancillaries and same is the case for Magnum.

You may be forced to use a 3rd party monitoring solution to bring all the elements of your system into one common dashboard.

If you have or plan to use a smart/managed Lithium battery like Pylontech, then careful thought is required how you will integrate the system and exert control of functions and behaviour when you are using different brand inverter and CC.

In the Victron world, a GX device is required when you connect to a smart battery and acts as active controller taking instructions from battery and telling the inverter and CCs what to do. This is the only method of working with smart batteries that Victron supports - so another brand inverter is a NO NO.

However a 3rd party solution like ICC or infact passive settings may be used. Just that system performance, reliability and safety may be jeopardized.

A Quattro has 2 inputs (Mains & Gen) and 2 outputs (Battery Powered & Pass Through). This is about the only notable difference between Quattro and Multiplus. Other than that, both may be used in parallel and split phase scenarios, similar ratings carry thesame load, software settings and hardware capabilities e.g PowerAssist are exactly thesame and none is more *rugged* than the other.

I have always found it strange that in Nigeria, the Quattro is more popular, very few people sell or use the Multiplus yet the very features that distinguish the Quattro mostly lie unused e.g the dual inputs are neglected in favor of an external transfer switch, the pass through output is left unused e.t.c

Good day house...

1) anyone has any technical view as to whether a Victron CC can be used with another type inverter. Have a client that's using Magnum inverter but need solar. Can't find Magnum CC (PT-100); looks like it's outta market. Next option I have is Victron SmartSolar CC, but I don't know if there'll be a downside using the Magnum inverter and Victron CC.

2) anyone here that has Automatic Transfer Switch for sale? I'll need like 4pcs

3) Biko, what's the difference between the Victron Multiplus and the Victron Quattro Inverters?

Thanks

Thanks very much Niyi...

Initially the client was thinking of doing Lithium later, as he's actually planning to overhaul his current battery bank (48V 1000Ah of 2V 1000Ah batteries). Told him the best option would be combination of Victron Inverter and Victron CC. But he's not willing to cast away his precious Magnum, which he just bought roughly about 2years ago at more than 1m (the newer magnum version).
After sourcing for Magnum PT-100 and couldn't find, I got in touch with Solar Depot sales rep and explained to her my intention of settling for the Victron CC with the Magnum since there's no PT-100 and she told me I need to use Victron CC with Victron inverter... But I guess, she was just trying to push the available products (all these sales people and their gimmicks, lolz) and that's why I actually wanted to confirm if theirs any major issue using Victron CC with Magnum Inverter.

And by the way, since the client won't be dashing away his Magnum inverter, he won't have any other option than to maintain Lead acid battery.

But if he later change his mind to do away with the Magnum, then I'll get him a Victron Quattro. But for now, he's settling for Victron CC to use with the Magnum, provided no issue.


Having said that, I need the following, if you have them

1) Victron Energy Smartsolar MPPT 100A/250V or 100A/150V - x1
2) Victron Smartsolar pluggable display - x1
3) Midnite Solar MNSPD 300 AC - x1
4) Midnite Solar MNSPD 300 DC - x2
5) Automatic Transfer Switch - x6

Cheers

There are 2 things here:

1. Low voltage protect of the BMS, if and when this happens the BMS shutdown power from going out of the battery hence your inverter won't even come on. The idea is for you not to get to that stage by doing point 2 below, but if it happens, the reset button or hoping that a high solar current will be sufficient to wake up the BMS are the options

2. Voltage cut-off by the inverter, if this happens then no issues as the inverter is what has stopped output hence your battery still have juice in it and will be ready to receive charge whenever it comes up. I recommend this and currently have mine set to 24v.... unfortunately that is the highest cut-off voltage that I can set on my inverter (and I think this is applicable to most inverters).

Abeg which inverter u dey use brand and model number

Valto:
it doesn't make sense if u are watching with external devices like DVD, dstv, gotv e.t.c. external devices wouldn't be powered once utility light is gone!

Sir if actually in real time it can last 5 hours then other device can be backed up with 40Ah-100Ah battery with 300w-500w inverter for small set up

Win-win

Yeah.

Penuelseun:
You can use a 5v input for your DVD if you can tweak the power panel

The DVDs usually have 220vac to around 16v or 12v DC (depending on the age of the device) output transformers on their board, there hasn't been big DVDs with 5v operating voltage.

The DC output them gets distributed by the power pack to various operating points like the DVD mechanical drive (which takes around 5v to 7v, the linear tray motor for disc eject (around 5v), the motor that rotated the disc itself (5v), the sound board (3v), the picture processing board (12v), if it has cooling fan (12v).

All that cannot easily be tweaked for 12v except you can get up to 4amps current of 12v. The best you can do is if you have 19vdc input which you can then distribute via limiting resistors and current dividers to power those various components.

Easiest way though is for him to get a DVD Walkman that works on just 3 pcs AA batteries. Chai! Nostalgia.

I still have those portable sony cassette player walkman DVD Walkman and an audio Walkman still lying around. We dey always take dem do big boys those days.

You go come dey waka like robot because you don't want to shake the device so that the scrathing sound problem wont occur, a problem later addressed with DVD players that come with ARS (Advanced Reading System) that digitally addresses that problem by reading and processing tracks few seconds ahead.

The GOTV decoders have external power pack (adapter). The ratings on it is usually 12vdc 1amp. So you just need to DIY a 5.5mm X 2.5mm DC plug that goes into the same input port for the adapter, then appropriately connect the positive and negative terminals to the battery. The decoder still works well on voltages as low as 9vdc.

Those old, big DSTV decoders have their power pack in-built, so it may be a bit of a challenge to have them run on DC volt direct.

There was a time the UPS in the picture powers a GOTV decoder and 14 inches portable TV/DVD for 3½ hours.

Correct me if i am wrong. The decoder is wired for dc operation. So the what happens is this: the followcome power cord converts ac to dc. Hence why the power cord is not an ordinary plug but a laptop charger type. That is why you were able to connect dc plug to it directly. Mine says output is 12v, 1.5a.

Ceaser has answered your question.

Please make sure the decoder is not connected to the battery while it's charging. I don't know if it can take up to 14.5V without damaging it. When I have a spare decoder, I'll do that experiment.
To be on the safe side, you can put a voltage regulator in between.

Correct. The adapter converts 220v to 12v to power the decoder.

I don't mean connecting the DC source to the GOTV adapter o. What I mean is that the same power-in port for the adapter on the decoder is the same place you'll plug in your 12v direct DC source. In fact by the time you are through with direct DC connection of the GOTV, you won't be needing that AC power pack (adapter) that comes with it, except of course you decide to cut off the DC plug end of the adapter to use for the direct DC connection. But I would advice it's better you get your own DC plug and solder in your wires to connect to the 12vdc source.

Correct. Although I've gone as high as 13.5vdc with it. What I noticed in such instances is the decoder unit getting hotter.
