campervan

Hello,

I am in the middle of making an elektrical schematic for on of my camperbuilds. In this build I would like to use an lithium battery.

I am using an Liontron 130Amp battery with build in BMS

Victron Smartsolar 100/20

Victron Multiplus 800VA

Victron BVM 712 Smart

Victron Battery Protect 3 x

Votronic B2B charger

300 watt Solar panel

To protect the LifePo4 battery I am using 3 x an Battery Protect in this scheme.

My question is: is this overkill and if not are they in the correct position?

The Votronic B2B charger wich I am using is not working via an battery protect, because it has a build in safety system and it will cut of charging when the temperature or charging levels are getting to high.

Because I am not using an Victron battery :( I can't use an Victron BMS or Mini BMS or VE-BMS etc.

Now I found another build online, although this is not with an LiFEPo4 battery they are just using 1 battery protect. Mounted directly on the battery +30, I thought an battery protect could only work 1 way, so either charging or de-charging protection? Does this build on the picture below mounted correctly?

I am looking forward to an reaction! :)

Thank you, Maarten

Hi All. The scenario is as follows:

We currently have a Cyrix-ct 12/24-230 connected in a Toyota Land Cruiser 79. This Cyrix charges the batteries in a caravan being towed (Via Brad Harrison connectors on caravan A-Frame). This works perfectly.

We now have a second bank of batteries in the back of the Land Crusier (2 x 125Ah). These power fridges in the back of the Land Cruiser.

Can the charging power of the Cyrix be split to charge the Land Cruiser's 2 batteries AND the caravan batteries (2 x 230Ah) simultaneously.... I have Argofet isolators available as well that can be fitted, if this solves the problem...

Thanks

I just bought Gel battery 130 Ah - BAT412121084. In the datasheet it looks like this is the C20 (in German K20) value. My charger requires the C100 (K100) value to be entered. I've read on some places that I can get it by multiplying 130x1.125=146.25 Ah. Is that correct or I can find more accurate source of this value ?

So I have a camper with a built-in AC - DC converter to charge the battery.

I want to add solar two of these https://www.amazon.com/Mighty-Max-Battery-Watts-Solar/dp/B01HHDC6NQ?pf_rd_p=ce125b32-6eda-4c46-b222-8e405f455858&pd_rd_wg=k4ssw&pf_rd_r=Z0KE2Y2H7DFZY2SPSC7D&ref_=pd_gw_hfp13n_bbn&pd_rd_w=ntgMY&pd_rd_r=fc184b3d-79e3-4052-857d-42f17883413a

and I was thinking about getting this one.. https://www.amazon.com/dp/B076N5PTBN/ref=sspa_dk_detail_0?psc=1&pd_rd_i=B076N5PTBN&pd_rd_w=XmWf8&pf_rd_p=8a8f3917-7900-4ce8-ad90-adf0d53c0985&pd_rd_wg=osiYm&pf_rd_r=AHXQEWK65NJKPRR4ZYFE&pd_rd_r=d20e2e79-72c1-11e9-88f1-c5c4d7a27c00&smid=AERMGYAT5R869

so I think how I want to set it up is.. both the output from the campers converter and the solar into the input of the victron converter.. then the batteries on their port and the campers load on the load port... I think..

But I think the input will be too high...

ultimately I want the BT of the CC to monitor the power consumption and battery charge. how should i hook this up for both boon-docking or powered setup?

Hi I have just purchased an Blue Smart IP22 Charger 30A (3) to use in my camper van. I was wondering what size cables should I install to charge the batteries? One battery is <1m away and 12V 75Ah, the second battery is about 4m away and 12V 100Ah. Also I guess it should be Ok to just ground the negative to the chassis?

Dear community,

I'm setting up a campervan and actually I'm curious about electronics but still have a question about this problem.

I want to charge my AGM Battery mainly via solar. Therefore I've got the MPPT 100/20. Input is the Panel, Battery is the AGM and Load are all consumers.

Parallel to this I want to charge the battery (AGM) while driving an the weather is bad so I can be sure my battery is loaded. Therefore I'm using the Orion-TR 12-12-9 with a manual switch.

Actually everything should work, but I'm not sure about the fused inputs and outputs and the solar panel.

What do you think?

Cheers Mario

Hi,

I am currently converting a van to a campervan and I am currently designing the electrical system. My estimation for a full day consumption is around 250Ah @12V. I was considering installing 640W of solar panels with 320Ah of battery. But to ease the initial investment I want to be able to initially install only 320W of solar panel and a 160Ah battery.

My requirements are in line with the general requirements for this kind of application, batteries to be charger by solar power, shore power and alternator.

After some research on Victron website I got this list of critical items:

Initial setup:

• 2x 160W-12V Mono 1480x673×35mm series 3a
• 1x LiFePO4 battery 12,8V/160Ah - Smart
• 1x SmartSolar MPPT 150/45
• 1x MultiPlus 12/3000/120-16
• 1x VE.Bus BMS
• 1x Smart BatteryProtect 12/24V 65A
• 1x Cyrix-Li-ct 12/24V-120A combiner
• 1x BMV-712 Smart

Upgrade:

• 2x 160W-12V Mono 1480x673×35mm series 3a
• 1x LiFePO4 battery 12,8V/160Ah – Smart (in parallel with the first one)

Any advice regarding my setup?

1. I considered the use of a Multiplus instead of a charger + inverter, is it the recommended approach for this kind of builds?
2. Are the monocrystalline solar panels recomended for this kind of application instead of the polycrystalline?
3. Is there any component on this list that is optional for this kind of setup? Or any critical component that I missed out?
4. Can I mount to lithium batteries in parallel, considering that they will have different characteristics? The second one could be bought years after the first one.
5. Is this setup valid if I use AGM batteries instead of lithium batteries?
6. The use of only one smart battery defeats the purpose of a BMV-712 Smart? Is the same information available is a connect to the Bluetooth of the battery?
7. How can I extract the raw information of all these devices to a server running in the van?

Thank you.

Good morning, I wanted to ask the victronenergy professional staff if I can use my Phoenix inverter, running with my camper.

The system consists of a 300 watt solar panel with mppt regulator, and the service battery connected to the engine battery with a 200 amper relay, like the victronenergy cyrix, but of another brand.

The Phoenix is connected directly to the service battery.

There are contraindications using the Phoenix with the engine running, and with the alternator??

I do not think so, but some told me not to do it.

Thanks for answering.

Hi,

Following a setup I am building for a campervan I have a question regarding the selection of the right MultiPlus for my application. [1]

I am considering the MultiPlus C 12/2000/80-30 and the MultiPlus 12/3000/120-16.

As I only have one LiFePO4 battery 12,8V/160Ah – Smart, can I use a Multiplus 12/3000 as the recommend maximum continuous discharge current for this battery is 160A? Or will be input current be limited to 120A?

Thank you.
