    Rosen Solar from Alibaba, anyone have experience?

    very specific to retiring in Belize... and for personal goods in the first year. Qualified Retiree Program. I cannot have any business dealings in Belize or with Belizeans other than as a user of services, have to inject hard currency into the banking system annually, and get a year of...

    Rosen Solar from Alibaba, anyone have experience?

    I have a broker on this end who looked over the B/L, but I also have a tax and duty free letter under my visa program, so I expect to be OK.

    Rosen Solar from Alibaba, anyone have experience?

    apologies in advance for going sideways on the topic... I am building in Belize where I can bring things in my first year with great tax incentives but after that warranty parts even cost crazy on tax and duty... I spent six months circling around between Rosen (48V vs 51.2V), Wisdom, and...

    Rosen Solar from Alibaba, anyone have experience?

    I was planning Rosen but got a better package from Wisdom/BSL, departing for me soon (at the logistics company). 51.2V 200AH - 5 plus a custom combiner and a sixth solo. the 200AH batteries were under $2000 when I bought but prices are up. Using them with Sigineer but they are identical to...

    Anyone have the BSL BATT - Lithium Batteries?

    I have placed an order and now they tell me there are delays for R&D. The person I was working with is gone. More as it unfolds, but I should have stuck with Rosen or Sigineer...

    Any Reviews on Meritsun 10kwh 48v from Alibaba?

    I have not looked at MeritSun but I have been comparing Rosen, BSL, Sigineer, and Polynovil 200Ah 48V/51.2V systems. The Rosen and BSL systems are also close to $2K, Sigineer a bit higher and Polynovil about 25% high. Leaning to BSL for their rack mount 10kWh x 5 plus combiner so far. I won't...

    Overpaneling generic questions

    You cannot exceed max PV power after adjusting from STC to your local insolation. Belize is +35% in May-July. You cannot exceed max open circuit voltage at coldest temps. You cannot exceed max short circuit current after adjusting from STC to your local insolation. If you obey all of those...

    off grid home system - comments on some details...

    I am pretty comfortable with the system on the right (rooftop panels, inverters, battery, etc. I am also pretty comfortable with the little remote power system on a 20' container for outdoor power. It makes sense to put the generator in the ventilated container and it makes sense to also use the...

    Trying hard to stifle a reflexive "China...", but I failed.

    Overpaneling generic questions

    Caution on MPPT - it is not limiting instantaneous current but is pulse width modulating it to look like an average current. The panels and the batteries are fooled by this, but the max short circuit current of the controller MUST be honored or you risk melting bond wires or damaging the...

    Sorry to hear that. Is 28 their full pallet for those panels or did they just load panels onto a pallet?

    Rosen Solar from Alibaba, anyone have experience?

    In Belize 12.5% GST and steep duties on components. Bona fide kits get favorable treatment, but I am just getting started with customs aspects. I expect 25% all in on the kit. Pallet of panels, six batteries, a rack, and four inverters MIGHT fit on two pallets and cost a bit over $1000...

    Rosen Solar powerwall - Where to buy?

    The price on Alibaba not for 48v 200ah battery price , just the advertise use to attract clicks , this is ruled by Alibaba, the real price based on quantity and capacity, sorry to misunderstand you. Best regards, ... basically Alibaba seems to encourage stiupid pricing to get clicks and...
