ECO-WORTHY Home Backup Power With 48V 100Ah LiFePO4 And 5000W 48V AIO Off-Grid Inverter

Generally exactly what I expected and so far working well. Delivery was speedy and effective, all the key components were present - including, crucially, the battery-to-inverter power cables which I feared I would have to source myself.

You do need a degree of familiarity with the electrical concepts to put it together and to be willing to navigate the various menus to get the setup right, as it does not come with a how-to-guide in the packaging, though if you go looking there are youtube videos. These were useful to confirm that what I'd figured out from the manuals was correct.

As delivered it lacks the battery-to-inverter communications cable but as I have no shortage of cat-5 ethernet cables, one of those worked fine.

The batteries arrived in an identical state of charge with 0v difference between them so they could safely be paralleled immediately.

On the plus side - installation and operation are good, although the data-logging dongle still refuses to set up properly. I don't care about that as I really don't want my inverter connected to the internet. The battery management via bluetooth and/or internet is good. A huge plus is that you can manage the inverter through the front panel and are not reliant on 3rd party cloud services which can fail (see the saga of GivEnergy recently). For an off-grid system it's absolutely crucial you can operate it with no internet.

What stops me giving it 5 stars? It's only been working a week and I'd need a year under my belt to give it 5. Needing my own communications cable was irritating. A setup manual for the whole combination would be nice. The inverter mppt tracker has a minimum 120v startup which means I need 4 panels on my shed roof not just two. When charging from grid or operating passthrough the inverter/charger appears to use 200W all by itself which seems a little on the greedy side. These are not show-stoppers, it works just fine, but they account for the 4 not 5 review as far as I am concerned. Four stars is pretty good.

The trailer needed 3.5kW for hot water, fridge and lights. Used gas for cooking. Batteries(47kg each) symmetrically disposed horizontal on left and right sides for balance when towing. Inverter central position on transverse wall. Used DC cables supplied for inverter connection. Battery separation needed 210cm (one-way) interconnect, and used double AWG 6 with crimped lugs and internal adhesive heat-shrink. Set battery charge to 40A and measured mains loading of 9.6A. Noted that charging current follows a controlled ramp from zero to full 40A. Checked battery current when supplying full 3.5kW AC load with mains OFF at 62A. Important to understand that if mains is present, the mains draw will be battery charging plus equipment, which can easily exceed a 13A domestic outlet which otherwise would be suitable for charging. This is not a problem if you understand how to use the system. When charging battery don't also have a heavy equipment load. It remains to be seen if transit vibration and forces will affect reliability. Trailer will cover ~100 miles per week. Frankly the engineering and the build look very good and I don't think I could have got a better system at anything near the price.
No problem with bluetooth connection for battery monitoring App. The documentation is adequate but suffers a bit from translation. There is no description of how the inverter works, but enough information to allow you to install it. My effort of understanding it is below and the numbers are specific to this particular application. I think the equipment would meet the numbers specified for it. I wanted some margin in the application. Overall, very satisfied and I will probably use this equipment again. This is gratuitous information and I take no responsibility for its influence, good or bad.

Timely. I haven't set up the system yet so will comment on that later

Easy setup instant solar power no problems
Inverter does as advertised couldn't be happier
