- Works with and without batteries: It offers conventional battery operation, but also has the option of operating without batteries. The system supplies the loads directly from the solar panels' output, as long as consumption is lower than solar production. If consumption exceeds solar production, the device triggers warning 15 indicating insufficient PV panel power and feeds into the grid if available to avoid power outages.
- Solar panel input up to 450 Vdc: One of the most important new features is that the 80 A MPPT allows for the connection of up to 12 60-cell modules in series, eliminating the need for a parallel combination box. All solar panels can be connected in series in a single chain, reducing wiring overhead and allowing for long distances to be covered without voltage drop. Parallel operation is also possible if the PV array needs to be supplied with 4500 W.
- Up to 4500 W for solar panels: allows management of a 4500 W photovoltaic field. The configuration of 14 panels of approximately 340 W, connected in series or parallel by 7 modules, allows us to reach the 4500 W capacity the device provides. This hybrid inverter would manage the energy to power both direct and surplus consumption for battery charging.
- Removable display and Bluetooth: The removable display allows the inverter to be located away from the mains, and the Watchpower app allows remote monitoring of device information via a mobile device. The team has access to daily consumption and production statistics.
- MPPT-regelaar met 80 A en tot 500 volt in open circuit voor het gebruik van 60- of 72-celpanelen in series van maximaal 12 of 10 zonnepanelen. De fotovoltaïsche omvormer heeft ten minste 6 seriële zonnecellen van 60 cellen nodig om de werkspanning te bereiken. De configuratie bij volledige lading bestaat uit 16 panelen van 280 W, 60 cellen in parallelle seriële verbinding met 8 fotovoltaïsche modules. De laadspanning van de regelaar bereikt 63 volt, zodat we lithium-, loodzuur-, gel- of AGM-batterijen kunnen gebruiken.

Good quality, bright, good light projection pattern, good choice for snowblowers
Color: 2Pcs 18W LED Flood Light, Color: 2Pcs 18W LED Flood Light
This review is ONLY for the Nilight model 1260LM (the package of TWO of them).
This product has a flexible design, allowing it to be used in a variety of ways when you want to add illumination to a vehicle of some kind. It can be used as add-on fog lamps for trucks and off-road vehicle, it can be used as headlights for golf carts and such, and it is a good choice for adding headlights to snowblowers. The two mounting brackets allow swiveling and angling up and down for best aim and illumination pattern.
Each 'lamp' assembly is mostly made of black anodized or black powder-coated aluminum, with a water-resistant design. The front 'lens' is Lexan or some other suitable clear plastic material with good, durable properties.
The manufacturer claims that the included mounting hardware (bolts, nuts, washers) are stainless steel, but they seem to weigh too little to be SOLID stainless. Whatever they are made from, they do not attract strong (neodymium) magnets. Because I bought the lamps to use on my snowblower, I decided to replace the included hardware with solid stainless hardware. The large bolts for mounting the brackets are M8 x 1.25 and the smaller bolts for attaching the lamps to the brackets are M6 x 1.0. I also chose to purchase the smaller bolts with 'cap head' bolts, because it make lamp angle adjustment much quicker and easier. Each included bolt comes with a flat washer and a split-ring lockwasher, and the large bolts also come with nuts (the smaller bolts thread directly into pre-tapped holes in the lamp bodies). The included lockwashers make sense for the main mounting bracket bolts, but there is no reasonable place to use the lockwashers of the smaller bolts. I inquired of Nilight tech support, and they clearly had never thought about WHERE those lockwashers should be used, and they concluded that they probably should NOT actually be used.
Each lamp has a short (perhaps 6") 'pigtail' cable coming out of one rear edge, and these cables each have a pair of wires inside; a RED one for + and a BLACK one for - . The user can wire these up any way that is desired, but probably they will be wired in parallel in most situations. I wish that the cables were longer; as it is, it is necessary to splice them to other cables in places that will not be hidden from view and/or otherwise protected from the elements.
These lamps are designed to operate on 12VDC power, although the exact voltage is not critical. There is no need to use a special LED power supply, since the lamps include their own internal power conditioning circuitry. Powering these from 12VDC, EACH lamp will required 1A of current, to 2A total when wired in parallel. This comes to 12V x 2A = 24 Watts.
In my case, I needed to power the lamps from a cordless power tool battery which produces a nominal 20VDC, which can drop as low as about 16V. Accordingly, I used one of the ubiquitous and inexpensive "DC Converters" (aka "DC-DC Converter") with an input having a voltage range that includes the expected 16~20V of the battery, and has a regulated 12V output, and has a Power (Watts) rating of at least twice the expected load, in this case a 60W one from Amazon. Since these converters have nearly a 100% efficiency, the input and output power (Watts) will be the same value, 24W. Doing the math in my case, an assuming an average battery voltage of 18V, the math is 24W / 18V = 1.3A. My battery has an Amp-Hour (Ah) of 4, so 4 / 1.3 = about 3 hours of operating time for the two lamps from a fully charged battery.
My only gripes with the product have already been mentioned:
- overly short power cords
- poorly conceived hardware 'package'; the smaller lockwasher are useless, and the associated bolts should have had cap heads instead of hex heads (I won't complain about the lack of sold stainless steel hardware, since that would have driven the selling price WAY up)

LOVE these LIGHTS !!!

i put 2 on the front of my 24" ariens snowthrower and it actually was to much !!! using one now and PLENTY of light !!! i have lots of dewalt batteries and i bought a adapter that allows me to put a battery in and has switch and fuse , wired to light and used one of my old 2AH batteries and it lasted 2.5 hours no problem , non stop . my newer batteries are 6 and 8 AH and last up to 8 hours before recharge . LOVE these LIGHTS !!! installing one on ladder rack on rear of truck . you know how many times that will be used on a late evening or early start so i can see to load or unload .
