3000W 12V low frequency pure sine wave off-grid power inverter 220V-240V AC with peak power up to 9000W (3kW nominal, 9kW surge power)

I've left it a while since buying this to comment - FOR the money, it's excellent... the best value 3kw pure-sine wave inverter (with a large surge capacity) I've seen...YES it's heavy but it does what it's suppose to and the fact it's got a built in charger means I can use the generator to top up my batteries without adding engine hours to the boat. It's handled everything I've thrown at it - warning me with a few beeps if I forgot and switched the kettle on whilst the tumble dryer was running ... it still worked just beeped to let me know it was too much load. The charger function is customisable to different battery types AND you can select the max rate ... in 15amp intervals I think (though don't quote me)...on my old generator, I had to limit it to 35 amp I think but with my new 2600, I can set it at max (which is either 70 or 90amp - can't recall)... either way, it's brilliant.ONE thing to bear in mind though is that it consumes 6 amps per hour just being on... you can leave it on power save mode (which varies between 2-3) but in that mode, it doesn't recognise small loads such as laptops or phones so you are better off using 12v converters for those. All in all a good product for a good price with good customer service from Photonic Universe.

We had a 5000w Powerjack on our boat, unfortunately the unit blew up & we needed a replacement in a hurry. This Photonic Universe one was in the UK & big enough capacity to cope with our off grid demands. Delivery was quick, the unit looked & felt really solid. We only use it as an inverter, not as a charger. We attached it with our original cables to the 1000ah lifepo4 battery bank and use our original wires from the AC out to provide power to our sockets, so for us it really was a drop in replacement. The powerjack may have been rated for more power but I feel more confident in this inverter. The powerjack used to sound like an aircraft carrier with something like the toaster drawing 1200 to 1400a, but this Photonic Universe one just purrs and on testing the body is barely warm. We’ve been using it daily for just under a month & so far we’re very happy.

It buzzes very loud when under a small load i.e. Hair straightenersIf you have it for a motorhome don't leave it on even with no load it drains 5 amps standing still

i have installed this inverter with a 225AH AGM. battery. Even after 3 days of charge, the battery indicator on the LCD still moves from left to right as it is still being charged. Is this normal???

I have fitted one of these inverters to a Globecar Familyscout L to power a 1000w microwave fitted under the rear bed and also various power sockets, it is running on 3 optima marine 5.5 batteries and a 500 amp megafuse for protection :) a really good inverter and the best i could find available. I used 25mm 230amp welding cable and soldered 25mmx8mm eyes to cable end lugs. Perfect :) batteries recharged daily with a 150w solar panel. It was also wired up to the shore supply inlet fusebox as it will also charge battery bank. as i only have 3 batteries connected and this inverter will run a house, i selected lowest charge of 18amps. User Manual is really good and is also available on the internet as a PDF.

No Ac input no battery bank cable's

Seems like a great unit. Solidly built and the internals look like they are up to the job.Cant wait to install and test it out

An absolutely fabulous inverter. Using in a motorhome conversion and it powers mains sockets with built-in USB chargers, a microwave, a 55" TV, Nespresso coffee machine, laptop and other battery chargers. The ability to handle surges such as start-up on a microwave is excellent and the fact it doubles as a house battery charger when supplied from external mains is extremely useful. The only downside and this is not the inverter's fault, is just how much power kit takes. Well worth buying a clamp meter to measure power consumption and write-up spreadsheet as a reminder. I have two house batteries wired in parallel and have the biggest single solar panel money can buy, plus a split charger from the engine alternator. This works well, but I reckon a few more house batteries wouldn't go amiss, particularly in winter where there is less sunlight.
