    Please help me reconcile difference between what I've read here about Growatt and what Sig Solar tech told me today

    As mentioned in my OP...:rolleyes:...I want to have flexibility to expand to a shade-structure or cabin in the future

    Do SCCs have a minimum amperage input requirement

    I understand: VOC input operates within a range, with minimum and maximum values which are strict for operation and safety respectively And Amperage input has a maximum value (which can be exceeded, although energy will be wasted)...but does it have a minimum value the same way VOC does? That...

    Please help me reconcile difference between what I've read here about Growatt and what Sig Solar tech told me today

    Thanks...in my OP I mention that I mostly boondock and only need AC about 30mins/day, so would rather not be draining battery 23.5 hrs/day

    The tech specified that the inverter had to be on during our call, not standby.

    Please help me reconcile difference between what I've read here about Growatt and what Sig Solar tech told me today

    The calculus for me is: cost/space/wiring/time savings vs performance/efficiency I haven't surveyed the landscape for a couple years since my last system and am trying to find the best solution for my budget & needs w/what's available now, may well end up with separates

    Please help me reconcile difference between what I've read here about Growatt and what Sig Solar tech told me today

    First, to get it out of the way, APL is a shorthand I learned here that I believe is used to describe AC input charging within a voltage range typical to the US: https://voltaconsolar.com/blog/knowledge-base/ac-input-voltage-apl-ups-mode/ Much more importantly, to me at least: we now have a...

    Hi--I'm not a total rookie, but still pretty new. I'm getting ready for my 2nd RV build--I'm planning on a 48V system so I can expand to a small cabin or shade structure down the road, initially based around one EG-LL 48V with about 800-1000W of panels on roof. I explained to the Signature...

    RV Battery System 12v or More?

    Bluetti spec is 2048Wh for AC200MAX

    RV Battery System 12v or More?

    Hi, unless I'm missing something earlier in the thread...AC200MAX is 2048 Wh...which would at least partially explain your results

    Safe to mount rigid panels on the over-cab roof of a class C?

    Are you getting pretty good harvest even though the panels are inclined? Thanks Are you getting pretty good harvest even though the panels are inclined? Thanks

    Safe to mount rigid panels on the over-cab roof of a class C?

    Thank you very much for this, I only saw the 2nd reply initially. I'll watch your video this evening, thanks again!

    Safe to mount rigid panels on the over-cab roof of a class C?

    Thank you very much for your reply. I went with VHB partially because that's what Will recommends for my situation...unless he changed position recently. My panels are rock solid up there, so far at least. VHB is used by some automakers in some situations where rivets used to be used...

    Safe to mount rigid panels on the over-cab roof of a class C?

    I have two 200W panels on the roof of my 21' class C Toyota RV, which has an aluminum roof. I mounted them on the flat part of the roof about 1' before the roof slopes to the over-cab, hoping to reduce wind drag. Now I'm thinking about installing two 100W panels, but the only space left is...

    Kisae DMT1250, can I lower the required solar input voltage?

    Thanks for your reply. The battery is factory-wired (under floor etc) to my DC distribution, and I don't want to tear the RV apart, so I need to power nearly all DC loads from the battery. Based on what you've said, the Kisae isn't able to increase voltage from an input, it only down-converts...

    Kisae DMT1250, can I lower the required solar input voltage?

    I'm hoping to charge my battery via the solar input, using the output of my Bluetti 30A output. The Bluetti default is 13.5V which won't trigger the Kisae's minimum of 14.5V, so it's not accepting the current. Can I lower the Kisae's minimum input voltage? I'm also looking into increasing...
