Hi,
What I like best is the hybrid load support feature. If you plug into shore power and have the (extra cost) remote, you can limit incoming amperage to prevent overloading the circuit. I generally run at 80% of what is available (24 amps on a 30 amp shore power supply).
For example. If I plug into a 15 amp circuit, I limit my demand to 12 amps. If I use more than that, with the load support feature active then I can still have the water heater and microwave running at the same time. The "extra" power is drawn from the battery bank. After the load drops, the Magnum recharges the battery bank.
What I like least, is a design error by Magnum. It has cooling fans. The fans shut down when the inverter is turned off. On one hot day, 2 years ago I had been using my generator (Yamaha 3000) and inverter together to run the roof air and make a late breakfast. The battery bank was "hungry" as I will NOT use the generator while sleeping. After lunch I turned off the air conditioner, shut down the inverter and turned off the generator, as I was going to be gone for a couple of hours.
When I returned, there were soot marks on the wall above the inverter. It had, because the cooling fans turn off, caught on fire.
There is no mention of this "feature" in the manual. I believe I was lucky my entire RV was not burned down.
To be fair, they did replace the unit under warranty.
Another dislike is on some gfci outlets, the Magnum causes the power to trip. This is totally random. At one location one plug would trip, and the other would not trip. I use a "patch board" approach so I can wire around the Magnum--but that defeats the purpose of having the load support feature. BTW load support is NOT voltage support.
In the old days when I had a 2500 watt inverter, I would sometimes do "double conversion". I'd plug ONLY the converter into shore power, and then plug the RV into the inverter. This worked quite well for me, especially on 15 amp shore power. However, the design of the Magnum has a HUGE inrush current, so the second the inverter is turned on, it blows the twin 30 amp reverse polarity fuses in the converter. That means I can't do double conversion as a "work around" when the Magnum is tripping gfci outlets, nor can I use the single dedicated 20 amp outlet that is only powered by the inverter. I have to "switch off" the converter to protect it, then use the outlet, turn off the inverter, and switch the converter back on.
Magnum does NOT recommend running the air conditioner from the inverter, which was something I wished to do. I was not aware of this for over a year after I had purchased the inverter.
If you wish to limit the charging current (my batteries recommend no more than 108 amps) the only way to do so on the Magnum, is to limit the incoming amperage. That is to say the least, annoying if you are on a 30 amp (or even on the 24 amps from the Yamaha generator). I heat 100% electrically, so turning down input amperage is something I avoid.
The Magnum does some "checking" before it passes through power. If the voltage is low, then a relay "clicks" and it waits for xxx seconds before it attempts to connect again. I had one cord where the tines on the male plug had heated. The Magnum would not allow the power through. I ended up replacing the end and then it worked.
In short, the Magnum, while a good product, has some foibles. I know from speaking to Victron owners that they have zero problems with gfci outlets.
If you still want a Magnum, then Imarine usually has the best price. Make sure to buy the top of the line remote to access all the features.

How old is your Magnum
What about the Magnum u donโt like
Thanks
