I'm designing a solar power system for my trailer, to permit me to power my computers during work hours and travel with my family. I want to insert an all-in-one and LiFePO4 battery into my RV's existing electrical system, which includes an AC to DC converter, but I'm not sure about the precise...

To make a 48V battery with at least 17.9 KWh of capacity, I intend to buy 5 packs of 4 Lishen/Eve 3.2V cells, which is 20 cells. I can make a 48V battery using 16 cells in series, making a 16S1P battery, but then I’ll have 4 cells left over, unused. I want to use those 4 leftover cells in...

Thank you for this feedback; I need it. I have not bought the cells yet. My goal is to have a battery with at least a 16.1 kWh capacity, to have 3 days' worth of capacity to handle a 5.38 kWh/day load. 20 3.2V Lishen 280 Ah cells would provide that capacity, but I've been unsure whether there...

I've made a diagram of the system I'm designing at https://diysolarforum.com/threads/5kw-48v-system-sizing-circuit-safety-check.23725/. I've found physical locations for each component to be mounted in the trailer. I haven't bought the AIO yet, but would like to buy an MPP Solar LVX6048...

He does exist. He was right to caution me that I needed to be sure the all in one has adequate ventilation to dissipate the heat it will produce; I think that was the main point he was making.

Oops...I should have said it's rated for 600 volts, not 2000.

Thank you. The manual at https://watts247.com/manuals/mpp/PIP-LVX/LVX6048%20split%20phase%20manual-20210312.pdf?x65773, p. 28, says the LVX 6048's "Max. Input voltage (Maximum PV open voltage)" is 450 VDC. So I believe the 260 V the arrays I'm planning could produce should be far enough below...

Just for reference, in case someone wants a text description rather than just a diagram, I described the idea in the original battery layout above at https://diysolarforum.com/threads/mixing-12s1p-4s2p-to-stay-at-48v-but-increase-capacity.23215/, and asked if it would work.

I should have said "280 Ah" cells; sorry for my mistake.

The fellow behind the counter at a solar store gave me some good advice, but stated a few things on which I'd like to get a second opinion. Here's one: The MPP Solar Hybrid LVX 6048 all-in-one inverter will waste excess power coming from the solar panels by burning it off as heat. Is that...

The fellow behind the counter at a solar store gave me some good advice, but stated a few things on which I'd like to get a second opinion. Here's one: 8 AWG wire could handle 9.6 A over 40 feet if there were only 1-3 panels put in series (creating 37 - 111 V), but since I plan to put 7 panels...

@Will Prowse Maybe you could find a feasible way to increase panel efficiency by cooling the panels.

From what supplier? I'm in the market for grade A cells.

I appreciate your taking the time to give me your opinion and recommendation regarding a better way to go. How are you arriving at that that conclusion? If that conclusion is correct, then I can see my original question is not worth answering. However, that conclusion does not appear to be...

I appreciate the recommendation to favor parallel strings. That requires buying more wire. Space and weight are at a premium on a camping trailer, so some might welcome a 10% performance improvement from a TCT array. The increased cost and complexity of a passive TCT configuration amounts to...

Background info I have an MPP Solar Hybrid LVX 6048, which uses Maximum Power Point Tracking (MPPT). TCT refers to a "total cross-tied" panel array wiring configuration, like the configuration pictured at https://www.researchgate.net/figure/Total-Cross-Tied-TCT-configuration_fig2_316359468...

The shading scenario I have in mind is an array on top of a camping trailer which will be in many different shaded environments, like forested campsites.

Hi, I'm designing a 5kW 48V system to upgrade my camping trailer from having 12V batteries and a 120VAC to 12VDC converter to having 5kW of solar panels, a 48V MPP Solar Hybrid LVX 6048 all-in-one, a 17.9 kWh 48V battery, and a 48V-12V DC buck converter. My current design is attached. Did I...
