I'm def reluctant to use the converters but I'm interested why do you think it will fail Mike? https://www.amazon.es/Convertidor-Regulador-Impermeable-Alimentaci%C3%B3n-Converter/dp/B0BD4PCDRM?th=1 Both panels connected in parallel, so 37v going in (input range 36-48) - 24v going out at 10amps...

this one fits the numbers better . . . https://www.amazon.es/-/pt/dp/B0BD4PCDRM/ref=sr_1_1?crid=2063D2XO2FN76&keywords=dc%2Bconverter%2B480w&qid=1690018024&sprefix=dc%2Bconverter%2B480w%2Caps%2C168&sr=8-1&th=1 I"m just a bit unsure if it's risky using a cheap device like this between my solar...

how about this? https://www.amazon.es/-/pt/dp/B089LRQM9Z/ref=sr_1_14?crid=2WSOEA2FBVC7R&keywords=dc%2Bconverter&qid=1690017437&sprefix=dc%2Bconverter%2Caps%2C208&sr=8-14&th=1 only thing is input voltage range is 40-60v whereas my panels ocv is 37 . . .

Thanks guys, I will go the 24v route if possible with the panels connected in parallel to keep voltages down, otherwise I'll be reducing from 74v (series connection 37 + 37), not sure is possible then to use a converter . . . So both those products I posted are limited to 120w, never saw that...

Hey, Looking at a quick get-around whilst I build my own system . . . I have a Bluetti EB70 and two 230w (37 ocv) used panels (spec attached) which are not compatible, can i use a buck converter safely to reduce the voltage going into the Bluetti? I have found these on Amazon...

could I use an external MPPT to reduce the voltage and charge my Bluetti eb7o that way? From my two 37v (ocv) panels . . .

No will be from the battery (terminals) to the input on the Bluetti which is a 7909 8mm DC female connector . . . custom cable most likely . . . Actually looks like there is a cable, battery terminals to cig lighter female socket, then I can use the supplied cable from Bluetti . . .

Effectively I'll be using the eb70 as my inverter . . .

Hey folks, I have a Bluetti EB70 and two 37v (ocv) panels which are not compatible . . . So I've ordered a 30amp mppt and about to buy a 24v 100ah battery or 2 x 12 100ah batteries. I thought after days of research I'd cracked it but now going round in circles again. With two 230w panels...

@mikefitz let me know on the above when you get a chance . . . I'm keen to order the bits . . . cheers

thanks for the feedback folks, it sucks without a fridge, i just got used to it! Really like this idea Mike! I can easily source a 12v 100ah battery, same as a car battery right? What PWM would you recommend for those panels/battery? I just have to alter some cables i.e. fridge to new battery...

hey buddy, did you find a solution? I'm also faced with utilising panels which are not 'compatible' with my EB70. Two used 230W panels with OCV 37V . . .

Hey Folks, Def a newbie/beginner in the Solar World . . . Starting with a small Bluetti EB70 power station thought it would be pretty straight forward, but two 230W used panels I bought were too high voltage, pic attached. So I'm currently borrowing a smaller panel (120W - but inputs seem...
