I have a Pecron Power Station E1500LFP which allows 32V-96V, 15A max and about 700W of solar charging.
I want to Car Charge using the available solar input port. But since the port calls for 32V-96V I don't think the Victron DC to DC converter Amazon.com - https://www.amazon.com/Victron-Energy-Orion-24-20-Converter/dp/B01BF5BU20/ref=sr_1_1_sspa?dib=eyJ2IjoiMSJ9.FuCLSZdzaxzEgnc4TuZhn9nJkeH-IdxEcUVqWiM6OEAXyejX-WdiyjiL1cqQZhfcqvUIkfM0UTL4h-4BblpR_g4eLueOgfTXEqLmc10R19KL0F3DwEqizEudk1KB_BlFGQsv1tFg46VHa4OeVOATj8KduWyS-PB5cRLXht6Ub4pItY5J_gabTyk92mWqzdIH5C1qByuiWhqVYu56Qq0gW80YYIZk9kDrHUf1LskqghA.ZcXg0mKdirAvKApinIM1DcFViGpC-SfOz3WwmvFiJ4Q&dib_tag=se&keywords=dc+dc+converter&qid=1715224752&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1&smid=A2VHGGOHXF24LJ which only outputs 30V will work well(although I've seen videos of Pecron working with 30V and even saw one work with a cheap 12V to 24V booster).
Now Pecron has come out with its own car charger that outputs 40V PECRON 500W Car Charger DC1242-500 for Cars, RVs, Trucks, etc. - https://www.pecron.com/products/pecron-500w-car-charger-dc1242-500-for-car-rv-van
It even has a adjustable Starting voltage range so it wont turn on until it sees the voltage you set.
My question is the input:
The input is a XT90 plug and the wire it comes with to attach to the Starter batteryseem really thin like 10g, per Pecron support the wire is 10mm sq or I guess this translates to 8g. I estimate a 16ft one way run from starter battery to the Car Charger input, looking up the online tables for 50A, with 3% voltage drop, I get a recommended 6g wire. Now with a 10% voltage drop I get recommended 10g.
I want to be safe and use 6g, but per the interwebs XT90 biggest wire it can fit is 10g maybe a 8g.
So what say you electronic gurus? Is 10% voltage drop adequate? Or if you recommend 6g how do I get the wire to play nice with the XT90?
