Thx Will ! You’re the man , viewed your DIY builds .. stayed with EcoFlow because they had the 5 year warranty…. But I’m thinking of doing my own down the line … great info you have provided :)

New update seems to keep them close … esp if I charge them to max ! Then they even up … hope that holds

Everything is working well … I have (2) Delta Pros , one charging the other … and one has an “ add on “ DP battery . I run 4x 260 watt ( in series ) solar panels to one DP , and 3x315 to the other . I have DP one connected to 30 amp RV plug to a manual transfer switch that isolates and powers 6...

I like the Internet gentleman ( Proser ?) and his setup(s) … definitely better solar INPUT options this route ! I just didn’t like the Amazon reviews and the lack of extended warranty….. Ecoflow has 5 year if you register through the website… most Amazon hybrid mpp controller / inverters seem to...

I’ve found with sunny So Cal days I can run 6 circuits ( about 65% of my daily use ) …both fridges and 2/5 bedrooms and garage ( but not 220 ) with the setup I e referenced above !! If I put another 6 circuit manual transfer switch , I’ll definitely upgrade one of the panel arrays for second DP...

I’ve been experimenting with the Delta Pro I bought Through Earth Tech …. I bought (1) DP and (1) extra battery , bought some used renogy 260 watts panels and started from there . I quickly found that cloudy days eroded the performance to 10-15 percent of specified watts , but they actually out...

Using VSUN 535 watt panels ( in series ) gets you 1605 watts and 49 Voc ( which is just under ) the Voc . This lets you “ max” the wattage . I’ve tried other panels / mfg of panels as there is a place that deals with insurance but packs / loss that has many and price is right . The VSUNS are...

I just ordered the DeWalt , but got the black one vs the yellow rack

Using VSUN 535 x3 gets you right on the money . Surplus place has them for 295/panel and you get 1605 watts and 49.1 Voc…with the 3 in series . These are the best quality , closest match , and the right price for our Delta Pros at current time and tier 1 and > 20% efficient … and I can drive 25...

The VSUN 535 I’m looking at are 49.7 Voc and 3 ( in series ) give you 149.1 Voc and 1605 watts , which I’m sure is at the top but within specs as the Voc seems to be more important . Also , these panels are > 20% efficient and tier 1 … I have 2 Delta Pros and (1) battery , and I use 315 x 3 on...

The Manual says to charge to 30% I think I Remember reading . If your man is not handy , pdf is on Google …

And two answer your question , 3 of those in series should be fine … I wanted to get 535 watt new panels at surplus place , but ended up buying insurance loss surplus tier 1 renogy and phono Solar …. But at 75.00$ a panel ! The 535 were great , but $295 plus tax each …I saved a few hundred by...

P.S I’m using 8 awg and I’m installing a double array shut off for servicing … Abs a 30 amp fuse on + side of each array for safety

And the Voc Volt restriction makes sense because that stresses the inverter more than anything ! That’s the open current … which on a cold clear am can exceed and stress the entire system . Good tip !!

That’s good to know Re : Amps , over paneling … It’s just a sizable investment … i don’t want to test the warranty… just yet lol ! I bought another Pro and use 1 to recharge the other and that adds solar AND battery capacity … Costco had pros with $100 remote for 2899 …. And 2% back if you use...

****Clean set up ! I’m using a reliant transfer , 2 Delta Pros ( to double Solar ) and used tier 1 panels I bought at a great price point . I had an electrician put in the transfer … and a weather resistant box as it’s outside next to panel . Wall pass through for my 2 Pros / 1 Battery I run a...

I’m using (2) Delta pro’s and a transfer switch , and one add on Delta pro battery . I put 4x 260 watt on my Delta # 1 , and 3x 315 watt on Delta # 2 . This was only a few hundred more than (2) add on batteries , and allowed more solar input . On a sunny day ( I’m in SoCal) I was able to charge...

Btw …. 8 awg wire should suffice …. And that’s about as big as I see made and connections for … I use 8 awg on both strings … 50 feet …. No issues . I’m putting a shut off switch so I can service both strings , and I put 30 amp fuse on + side for added protection ( although doubt you need )

You’re not calculating correctly. And 17 amps exceeds the inverter, which says “ 15 max “ …. That will NOT be good for the inverter longevity . I have same panels , and as stated , I run 4 x 260 “in series “ for 1040 ( I pull 1100 in bright Sun ☀️) And keep the amps at 8.5 .Eco Flow runs...

I have the same panels …. ( I’m in So Cal ) I run them in series on one of my Deltas ( 260 watt x 4 , in Series , Voc at max 151.2 watts 1040 ) . Did you buy panels in Santa Paula ? That’s where I got mine fyi . This setup works and I’ve been running 2 months . You can run “ in series “ and x...

PS I got a great deal on the panels … used from a surplus dealer …. 75.00 /panel for the 260 watt ( tier one btw ) and 120/ panel for the 315 watt ( again , tier one phono solars ) … this kept over cost done , used a ground set up , had the manual transfer switch with 6 critical circuits already...

I run a delta pro into a manual transfer switch using a wall pass through and the 30 amp RV plug , and in the circuit that has the gfi plugs in bathroom , it tripped overload on delta pro immediately! No issue on other circuits… and those run 75% of my needs ( refrigerators and central heat ) ...
