    Mismatched Panels Series Parallel safety check

    I currently have the 360w and two 200w in series with a fuse to a Growatt 24V SPF 3000TL LVM, 80A MPPT 2KW PV, PV Input 30-115Vdc, PV Max input 145Vdc. I think I can add the two 400w in series with a separate fuse in parallel with the existing string. I would like a sanity check before I risk...

    10,000 watt 12 Volt inverter

    I saw a 10,000 watt 12 Volt inverter for sale. This has to be a Joke there is no safe way for a normal person to power the thing. With a 20,000 surge this thing could draw over 1,600 Amps https://www.target.com/p/wagan-proline-10-000w-inverter-remote/-/A-52353288#lnk=sametab

    Cheep easy way to insulate a shipping containers

    I looked up the price after posting that and was shocked. I would consider DIY, that yellow core looks like it is made of alternating directions of cloroplast, a 4x8 sheet costs around $20 at home depot and could make a core 1 foot square and 5 inch thick.

    growatt 3kw Helppp...?

    Without more detail, it is hard to be more specific than check your connections, circuit breakers and fuses. https://bigbattery.com/product/24v-lifepo4-power-wall/ If this is the one it has two on the inside and one on the outside.

    @David Smelser Looks like you could fit 6 of those Miady batteries in one of those boxes without the fuse box and 12V socket, could you measure for me? Thanks.

    Battery storage over winter and water level drop

    Cody's Lab in storing a starting battery fully charged it then drained the acid and stored it separately. He claimed it can then be stored for years without being damaged.

    Charge 12V from 24V battery

    I have a SLA 55Ah to run a CPAP overnight in case of a power outage. I currently keep it on a wall float charger and disconnect it and move it when I want to use it. I have a controller and 400 watts of solar that can recharge that battery in a couple hours. I was thinking of getting a 24 volt...

    Charge 12V from 24V battery

    kernel Thanks for finding that. I was looking for something with fewer features. What would happen of you connected the panel input of a cheap PWM charge controller to the 24V battery?

    Charge 12V from 24V battery

    I know about the battery Isolators, that Will has on his site, but they all seem to be 12V to 12V. https://www.mobile-solarpower.com/battery-isolators.html I could use a 24V to 12V converter, to feed the battery isolator. $140 - $200 Or an inverter to a normal 12V battery charger. As low as $50...
