I ordered an oscilloscope to test it

I ordered one as soon as I saw it. It will be here Monday. DC HOUSE 48V 2000W Inverter 25A Charger

about 2 weeks ago i got 4 for $350 from Temu thanks to a $120 new user coupon. I have had one hooked up to my ham radio that I use a couple hours a day and it seems to be doing good. They all tested 13.25v.

Looks like there are just a few left

I ended up going with a 48v system with 1500/3000 watt inverter, 4 320 watt Bifacial panels, and a 150 45 mppt scc. After all the advice I think I am going with a Bussman JJN-80. I jumped the gun and bought a Zookoto 150VDC IR10KA 80A Class T Fuse before I new what I was looking for. Link below...

from what I have read DC House and Eco-Worthy are the same company. Eco-Worthy has inverter chargers and they have good reviews.

Attached is my wiring diagram. I have research for many hours so hopefully it looks good. If you have any suggestions please let me know.

the charging cord and 2nd outlet need to be hardwired. The picture looks like it comes with the charging hardwire but I am going to get a really heavy duty extension cord to cut it in half and use that for each.

Battery to inverter

After looking at Wills videos do I need an Automatic Transfer System like the one shown on the video "DIY 2000 watt, 24v Solar Power System w/ LiFePO4 Batteries"

I guess I am thinking after a couple fuses I could buy a breaker. If a blown fuse is rare then I am fine with that type of money.

that is still $30 a pop. Is there a real reason not to use a Blue Sea breaker?

I have decided to use solar power for my man cave. During the winter my maximum watts are about 150 due to me heating with propane. Summer will be the same 150 watts plus a Midea 8,000 btu inverter ac. According to Midea the total start up watts is 710 and from what I have read ongoing is about...

I going to put the panels on a movable setup so I can turn them

Are the used 250 watt panels for $50 from Santansolar.com worth it?

There are three different numbers that are volts how many are they actually? What size battery do I need with them?

Can everything go to the shunt like I have it?

Has anyone tried the ZOOGAMO 12V 200Ah LiFePO4 battery from Amazon? Seems like a good deal but not sure.

I am going to use 6 gauge for scc to battery and everything else 2 gauge. I don't want bus bars or a battery switch. Does anyone notice anything that needs to be fixed?

4 Seraphim 305 Watt 60 Cell monocrystalline solar panels for sale. New never used, I had big plans but they fell through. $800 obo. Located in Mayfield KY

Xijia 1500W

I am building a 48v 200ah battery and I was wondering what size Daly BMS to use. I have been looking through the forum and have seen that people say go bigger. Would it be ok to go with a 250a?

i found 2 Bussman JJN80 fuses for $30 from an eBay seller with 99.8% feedback and 11k items sold.

i found a calculator for wind load and each panel is 25 lbf. How do I find out how much downward weight i need based on 25 lbf?

i am doing a 48v system with 4 12v batteries in series and my inverter is 1500/3000 watts. I am using 4 awg wire from battery to inverter.

Did you end up buying it? If you did how is it?

It's for a 32" tv, a socket fan/light, lamp with led bulb, phone charger, and laptop charger

I live in the country and my closest neighbors are about 1/4 mile away. It is blocked from wind pretty well to the south due to house. Would I be better off using 4 or 5 ground screws per array instead of the buckets?

I need right at 5 kw daily. After some research I have learned that the worst day in Western KY gets 3.5 hours of sun. Would 2000 watts of solar and 2 200AH 24V LiFePo4 batteries be enough, what would be a good all in one unit for me, and are the used 250 watt panels for $50 from Santansolar.com...

I ended up contacting growatt about returning it and for some reason they told me to just keep it and they refunded my money. My new plan is to use it to power everything I need but a/c and build a larger system for my a/c.

Check out the other options in this listing because some of the others are also on sale. Amazon Blue Sea Systems 285 150a

I was thinking about a Vevor inverter/charger and an Outback charge controller.

I chose a scc that size because i am going to add panels little by little as I get more money

SOLD!!!!!

I found new Adani 365W Mono Solar Panels on eBay for $165 with deliver to residential with liftgate: Estimated $200 - $340. I was wondering if Adani is a good brand and if the price is good?

Based on that I should have just enough for the worst month, December and January. Just to make for sure I think I will add a couple 100 watt panels.

I ended up buying 4 new Seraphim 305W panels for $120 each

I need a 60 amp fuse between mppt and battery but unsure of type. The 150 45 Victron manual does not specify type of fuse just amps. I already have an 80 amp class t fuse for battery to inverter and 30 amp breaker for panel disconnect. What type of fuse should I use?

Thanks I ended up ordering a 100a Overkill 16s BMS

All of them seem to be for bigger fuses.

I have 4 12v100a lifepo4 batteries and am trying to decide on 12v 24v or 48v. I am only powering a 100sq ft man cave with a tv, phone charger, laptop charger, 2 led lights and a 5000 BTU window a/c for no more than 6 hours. According to my kill a watt the ac runs 400 watts full blast and 825...

Based on my research I only have to fuse based on continuous wattage. So I only need a 60 amp fuse. What type do I need based on that?

Would 4 gauge still be ok or do I need to go up to 2 gauge? My inverter peak watts is just 3000 so I will never get close to 110 amps and 4 gauge is 100 amp.

I just ordered 4 305W Seraphim panels and 2 24 Volt 200ah batteries. I will be needing about 3.5 kw a day and I was wondering how to size an all in one system. Seraphim Panels 305 Watts Open circuit voltage (VOC): 39.9 V Max power voltage (VMP): 32.3 V Short circuit current (ISC): 9.76 A Max...

Updated diagram is attached. Thanks for the help so far.

I have decided to build my system myself instead of going with an AIO. How do I get the capabilities of an AIO charging batteries with grid or generator and also using the power from grid or generator to power my system?

Nice those batteries would be all I need for my off grid cabin. Where did you buy them from and what brand is the inverter?

After researching the forum I found 4000W inverter/48V battery = 83A So I would need a bms 16S48V 100A. So is that number correct and what brand should I get? If I use Over Kill BMS like Will suggest, is a 100A all I need.

Anyone try these batteries or is this price to good to be true?

I need 4.5khw a day. I am going to have 2 24v 280ah batteries, and 4 Seraphim 305W panels. What size all in one would I need? I was looking at a MPP Solar LV2424.

can solar panels and grid be put in pv input together?

I was wondering what the thoughts are on inverter/chargers vs auto transfer switch. I am using lifepo4 48v battery and from what I have researched I need something that has programming to make sure voltage are set correctly for float and charge.

I have an existing cabin and was wanting to run power to it via solar power with a budget of $4000. I want to power a small fridge, a fan, tv, xbox, and 2 led shop lights. I was wondering if it would be safe if I plug a power strip in the inverter that has 15 amp receptacles and run what I need...

I have had to move my man cave further away from the house so an extension cord is not practical. I have a propane heater and Vita550 with a 100 watt panel that powers everything in my man cave this time of year. I need to save up money for a setup to power my air conditioner only since I will...

What about a Bluetti?

I guess I am thinking that in the video Will has about auto transfer switches that when the battery is low the ats starts powering the load and also charges the battery. With me thinking that I guess I was wondering if ats vs inverter/charger has any advantages over the other.

Which inverters have the internal transfer switch?

I have 4 320 watt panels and I plan on using 2 solar bracket kits and attaching 2 panels on each. Each leg will be attached to a 5 gallon bucket of concrete using 4x4s and simpson strong tie wood to concrete bases. I live in Kentucky so we have no hurricanes but we do have storms with occasional...

This is a man cave so at the most I will use it 3 hours a day.

yes. is there a reason not to go with the inverter/charger

vs separate charger and ats. I am setting up solar for a cabin and I was wanting a way to charge the battery with a small generator for days with little/no sun.

from what you can tell don't you hardwire the charging cord and one of the outlets?

Is there an alternative fuse or breaker suggested?

Would 2000 watts of panels be enough since what I have read Western Kentucky at worst gets 3.5 hours of sun a day during winter

I used app.diagrams.net. It is very easy to use.

Why do you say that?

Im already using 4 awg so 100 amp fuse will be no problem. Any specs for the fuse that I need to look for?

Was wondering what brands of inverters charges mppt and batteries you all recommend.
