OUPES's current units run from 288 Wh to 3,072 Wh. Every unit uses LiFePO4 cells, rated between 3,500 and 4,000 cycles. Maximum solar input spans 240 W to 2,100 W, which is the figure that caps recharge speed whatever panel you attach. 4 of 6 accept extra batteries. 6 state a UPS switchover time (10 ms, 20 ms).
Whether the top pick is the right one depends on your load: put your devices into the sizing calculatorand the fit table will say which OUPES units, and which rivals, clear it.
OUPES Mega 1 at $0.68 per Wh. Value only matters once a unit fits: use the calculator to check capacity, continuous output and surge against your devices first.
One whose surge rating clears the compressor's start-up draw and whose capacity covers the days you need; the refrigerator guide lists every unit that clears one, two and three days, and the home-backup page sizes the whole kit.
No brand does. A dash in a cell means OUPES does not state that figure, and the table never fills it in from a retailer or a review.
