Review on 🔋 WZRELB 5000W 12V Pure Sine Wave Power Inverter - Solar, RV, DC to AC Power by Joe Unruh

This unit is in a remote outbuilding, the location makes using a shore power source impractical. I used to use a "cheap" 400/800w modified sine wave inverter to power my lights, but any load other than a small drill would cause it to go into failure mode and I sat in the dark with the LED lights flickering. The building is hooked up to a generator, which works great (and gives me a reason to keep it running regularly), but it's a step up when I just need to switch off quickly. Sometimes I found myself grabbing a handsaw because it was easier. This unit comes installed with a 1/0 wire, a 400 amp fuse and a switch (no pulling unless I turn it on). The hard-wired connections on the inverter are used to connect it directly to the fuse box, as using the outputs on the inverter only supplies half the available power per output. As this building is fully mains powered, power from the junction box means that all sockets, interior and exterior lights, etc. are working. I can use a 1/0 cable since I have very short runs (and the cables are the same length). If you have a larger distance between the battery and the inverter, you need a larger strength. The batteries in groups 27 and 29 are connected in parallel with the solar panel to keep them charged. If you want to use it for a long time, you need more batteries. There is no switch, so the "inverter" and "generator" switches are mutually exclusive, turning them on at the same time can end badly. Luckily, it's difficult to accidentally wheel a generator outside, leave it running, and plug it in, virtually foolproof. The second figure shows the idle power consumption for this device, 2.37 amps/29.3 watts. For comparison: A modified 400/800 W sine block has an idle load of 0.73 A/9.2 W. In fact, 10 times more power with 3 times less idle consumption. I tested this with a battery meter sold here at Revain which works great but only has a 100 amp shunt. A permanent installation requires a 500A shunt, so on subsequent exposures (and under load) the meter simply measures static. I wasn't sure what would happen if I ran the big saws, I didn't try them before shooting. Video so you can see the first attempt. What you don't see is my smile, at this point I had several hours of installation. The starting load of these large motors is many times the rated current draw when they are running, but the inverter didn't bat an eyelid. Pure sine also means cleaner performance, so even motors typically run with less heat, the benefits for more sensitive electronics are already well known. I haven't tried using both saws, but from a practical standpoint I don't work that way, but I did enjoy turning on the TV, lights, heater fan, stereo, etc. while filming a video, which is pretty decadent !
