Charging a Bluetti AC200Max from a roof mounted solar panel on my Ford Transit.

Hi,

After a lot of research I bought the above power station with the intention of using it in my Camper Van (rather than a leisure battery). So what I want to do now is to install some solar panels on the roof of my VAN to charge the power station. Can anyone give me some suggestions please? I don’t know where to start with this.

Thanks

Hi, ollienorth. l have 3 Renogy Solar Panel 200W (69.9L x 3.5W x 149.1H centimeters) on my self-build Renault Master MWB Campervan (2 off/400W) connected to my Bluetti AC 200 MAX which is more than enough during the summer. The 3rd I use to charge my EB 70 (2)

I put 2 of the Renogy 150W CIGS panels on the roof of my Leer cap. They have worked great so far ( 1 month). They are in series and charge my Bluetti AC200 MAX with no problems. CIGS panels are expensive, but they are very light, very tough, and solar-efficient. I’m 6’ and I can barely detect that they are on the roof.

With reference to my post near the bottom of the thread on using 240VAC (or U.S. voltage) through an inverter when driving

Did you guys consider the static electricity buildup?

Brilliant that sounds like the perfect solution. I assume they just plug straight into the Bluetti with nothing further required? Is the adhesive on them good and strong? Wondering if the UK weather will cause any problems in that respect?

Thanks

Nothing further required as far as plugging MC4 cable into the Bluetti’s PV port. Since the AC200 MAX has its own MPPT controller, no problems. Renogy does have its own “MC4” gimmick in that the Renogy MC4 connector will connect to the Bluetti MC4 connectors without a problem. However, disconnecting the Renogy and Bluetti (or anyone elses MC4 connectors) can be difficult because the normal MC4 disconnecting tool does not work with Renogy MC4 connectors. You have to use Renogy’s connector tool to separate them from normal MC4 connectors OR use an Amphenol H4 connector tool. A small, flat blade screwdriver will work, too.

The adhesive on the Renogy CIGS 150w panels is very, very strong. I also purchased a roll of Eternabond double-sided roof sealant tape just in case any difficulty came up. After a month, the panels are still strong on the cap roof. My panels did NOT include any documentation or installation instruction. I watched several Youtube videos for installation tips.

hey smycker I also have 3 100 watt solar panels 1 of the being the same brand you have. My question is how do i wire to get my most wattage. I have for now a 350 bluetti watt solar panel connected to two 100w by solperk. i have them all 3 connected in series but im getting 160 watts. I am supposed to get 550watts i dont get it. em i suppose to have extension cables does the awg matter deppend on the wattage of the sollar panel? using the 350w panel by itself give me around 300w sp i dont get why connectong the 3 in series give me no more than 200watts.

Hello
The problem is that panels that have different characteristics should not be connected together. In this case, your PV350 panels must deliver something like 10A and your Renogy panels must deliver perhaps 5 amps, and therefore your RENOGY must limit the amperage of your PV350, which cannot deliver the maximum power.

A solution: buy a bluetti D050S and connect either your two 100 RENOGY panels in series, or (exclusive) your bluetti PV350. You connect the other(s) solar panel(s), which are not connected to the D050S to the solar input of your AC200max. So you separate the different panels which are connected either to the D050S or to the solar input of the AC200max.

Hi Frank27, I agree with (Snips1) solution, if it were me I would connect the two 100w Solperk in series to the AC200 Max solar and the 350 bluetti panel via the D050S into the main 240 connection. I’m also an owner of a D050S because I own a AC200P which only takes solar above 35v.

Hey Snips1! Thanks for saving me on this situation. It makes sence to me now. I just ordered the part so I can connect the two 100w solperk. I will keep updated once i receive it amd try this method!

Hey smycker! I will try either method aslong as it works! I also agree with snips solution. Quick question, Can I connect like two differently solar panel brands all 100w to that device D050s?

I can answer your question.

If you can’t find exactly the same panels, you can try to connect only in series panels of the different brands which have the same current (closest Imp) : this is your second option if for whatever reason you cannot find the same brand panels.
if for example you have a panel with an Imp of 4A and a second panel of 5A, mounted in series, as the intensity of the current which circulates is identical for the 2 panels, it risks being at best 4A for your second panel with an Imp of 5A so you lose 1A for the latter (20% less power): so you understand that if you cannot take the same exactly identical panel, the least bad solution is to take a panel of a different brand but having the same Imp (or very close).
Finally you must be careful that the sum of the Voc of your panels in series does not exceed the maximum voltage specified for the solar input of your ac200max (145v) or your d050s (60v)
