Can you say more about what you mean here? Googling "Alu anglign" doesn't find anything... I'm currently working on an improvised off-grid panel install and am interested in options!

Hi there, I am planning to build a portable solar generator. Both the battery and the solar panels need to be portable - the panels will not be permanently installed (they will stay in place for about 10 days, then moved). I am requesting critiques of my design - would love to know where I'm...

@BentleyJ where do you see that? I searched the manual for startup and see 120Vdc (I'd like you to be right, lower voltage would suit my use case better!):

I just want to confirm something with the EG4 3kW Off-Grid Inverter... in the manual it says "PV Array MPPT Voltage Range" is 120VDC~450VDC. This means that you must supply at least 120V from the panels before charging will start, correct? So if I had, say, three panels with VOC 50V, I'd have...

We've been running with a 3000W for years, currently thinking of going to 4000W. But really I need to run the numbers and figure it out properly. Thanks for the links to Current Connected, I wasn't aware of them! I was thinking of having the battery bank be 24V... hang on I'll attach my WIP...

Yes we'll need an inverter. I wasn't planning to DIY the battery, but buy something like the AmpereTime battery in the link and wire them up in a bank. That said, I'm curious about the DIY option... I'd like to hear more!

Hello all, first post - new member in Seattle! I'm hoping to talk through designing a solar rig for Burning Man. We've been running a ~5kWh solar rig using SLA batteries for years at Burning Man, this year we want to upgrade to lithium (the SLA batteries are getting very old and we don't want...
