    Please help me size my mini-split for older RV

    In this same RV I had a 13.5K roof A/C that kept me cool during 111 degree heat wave....but not with much to spare. Yes, removing and re-installing is not ideal...but I may do it if budget is too tight to buy another mini

    Please help me size my mini-split for older RV

    Thank you. I think my roof will be pretty good with panels & highly reflective membrane elsewhere. My insulation however is pretty much 3/4" styrofoam type stuff, and I have big old-school windows as well... I'm leaning towards the 12K currently. The install is reversible and I could put it...

    Prices dropping, will this continue?

    I heard an analyst on the radio say that the declining prices of solar panels will likely end by the summer. Perhaps this might apply to batteries as well

    Signature Solar EG4-WP 48V -- does anyone have experience w/the new 200A BMS version?

    My research on the earlier model w/smaller BMS has made me wary...but the new version is $999, which is tempting. Also, is a "dumb" battery like the WP going to be able to make basic communications w/my AIO which will likely be the MPP 3048? Would an EG LL or Lifepower4 be significantly...

    Please help me size my mini-split for older RV

    Thanks for all the replies Partime, this makes sense and would likely more than nullify the 1 point superior SEER rating of the 9K Eggo, I think I can get 1200-1300 up there and still have room for a maxxfan...and buy another 5.1Kwh if necessary WME--I took off the old AC yesterday and am...

    Please help me size my mini-split for older RV

    I'm full-timing in a 1989 Toyota camper, about 21' long... the cab & over-cab areas are sealed off with thick blankets, so the area I'll be cooling/heating is about 100 sq ft, 12x8'. I'm looking at the high efficiency EG4 units, debating between 9K and 12K, 115VAC. The 9K is rated for "rooms...

    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...

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

    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?

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