Thx everyone for your input. Good testing environment. 25+C and sunny for 4 straight days. Pretty nice for Alberta in April.

Ya I probably won’t live that long anyway. So do you see any issues with 2P2S as long as I get what I need?

Yes from the panels. Other guys suggest panels wired 2P2S. Seems logical through testing. issue now is the controller. Probably back to your previous concern with Epever tracking. It’s always been an issue with previous FLA batteries not going to bulk properly and not maintaining float even with...

Mmm that could be it. Can you tell anything from this pic? And in the long run would it make a difference in this application? The series seems to be paired sideways.

Connections are all covered. Looking for suggestions for installer to check. Update today, controller wasn’t going to boost, changed boost recovery to 13.5 and then got 15 amps at 40 volts. Tells me both series strings are operating correctly. So on next test, I covered one panel in each...

Battery 280 a/h lithium. About 60% when started charging. Controller set for 14.2, was at 14 pushing 25 amps at start. The 8 amps was from the panels at 42 volts. Still half expected production. I did put the inverter/ charger on for a bit later on to test and it was pushing the 30 amps set...

Thx I’ll check again tomorrow, expecting full sun again. So cover, then disconnect and reconnect panels. Should I turn controller off and on as well? I did allow 1 hour for results between tests but did not switch off/on panels.

Thx I figured wiring, what did he do wrong you think? No shade for 2 days, until dusk, so still could be diodes? Disconnect happened during full sun.

I have 4 of these panels Installed (not me, apparently 2S2P) so expected max 42 volts, 18 amps) identified for experiment as 1,2,3,4. 1-2 in series, 3-4 in series then y connector parallel to controller. Epever 100/40 controller. Admit up front I did not monitor amps, just voltage. Operating...

Thx for that info. Yes the Bluetooth monitoring is a distinct advantage. Can alberta lithium confirm your experience?

Thanks to those that addressed the direct question I asked and/or offered alternatives.

Thanks Do you have any pics of delivered product? Or know what cells/BMS are used?

Replacing my FLA batteries in my RV with lithium. Down to these choices, based on my requirements, location, and budget. Canadian dollars, both are free shipping. I will probably be getting 2 for parallel connection. SOK 206A/H (SK12V206) @ $1345 and the Renogy 200A/H (RBT200LFP12-BT-CA) @ $1249...

Perfect thx a lot. I will do the 2S2P

I am getting 4 new 200 watt panels installed on my rv roof, and want to know best way to connect them, 2s2p for 43 volts or 4s gives me 86 volts if I’m calculating correctly. Is that too close to the 100 volt limit of my controller Epever Tracer 4210A? Pic of panel label below. Wire length 30-40...

As in the title, IC2000 inverter/charger. Rv, ran a/c plus charging through generator. Too much load I guess, a/c shut down and inverter had one green light blinking. Generator ok. Shut everything off and reset inverter. Good and working. IC Remote though shows red light. How to reset? Cheers...

Their website shows only small cylindricals https://lithicoretech.com/

My rv is parked in year round campground. I have 2x280w panels that have been on the roof for 3 years. They are mounted on adjustable aluminum angle frame with padded feet. Sandbags to hold them down. Now the trees have grown so much the harvest is nearing half the original, and of course our...

Thx Bud Ended up disconnecting the wires after pulling the controller from the wall. Just thought there might be a way to flip a switch on the controller. Panel is on the Rv roof and no breaker installed.

Doing some troubleshooting on the batteries but need to turn off the solar. Not supposed to disconnect from the battery. Can’t figure it out from the manual.

Care to share where you found this deal?

Can I butt in and ask Phero where you got those battery boxes?

I have solar panel wires and LTE antenna wire together down vent pipe on my RV with no ill effects on either.

thx much I am near there

Is that Canadian or US dollars, and what part of Canada? thx

Blue Sea busbars are highly regarded. Nice tinned copper with big lug posts. bluesea.com Some marine supply sites sell them as well.

Well that was fun, posted from my phone, it got confused. Anyway, when unplugged, 12 volt comes from the batteries to the trailer. When plugged in it comes from the converter, which also charges the batteries while in use. From there you can add solar to charge batteries and inverter to invert...

The 12 volt comes straight from the battery to the trailer. Same as now if you are not plugged into shore power.

Yes, can plug in 50 amp cord to shore power, or with 50/30 adapter to generator. It does invert power from batteries when not plugged to AC input. Solar goes direct to batteries. Inverter Charger used to supplement when needed. Adjustable charging profile, inverter and solar controller. Use...

Yes I always get confused with A/C and AC, my bad.

I have this in my 50amp RV: https://gpelectric.com/products/ic-series-2000-watt-inverter-charger/ A/C passthrough, hardwired 2 legs to RV panel. Charger is programmable via remote. Solar, Portable generator for air conditioner and supplemental charging when needed. Removed the converter.

Yes, I am using Chrome. When i click on any attachment, link or pic (except full size ones) in forum posts it opens to a nice size automatically in a new tab. Maybe it's how it is loaded? Or Chrome? Don't know, this is what I am trying to achieve.........

How about this one? Copy paste PDF from desktop....

The diagram is a work in progress.... This is an experiment in posting pics and PDF's The wire gauges are in the text description now though. Thanks for the input
