The MS Series modified sine wave inverter/charger is powerful, easy-to-use, and best of all, cost effective.Optional ME-RC Remote Control #57253 (sold separately) monitors inverter and charger status and offers finger-tip operation, with one-knob programming. Power Factor Corrected (PFC) Charger: Our PFC charger is built into all of our inverter / chargers. It uses less energy from a generator than a standard charger – using 25-30% less AC current than standard chargers. Magnum Energy Promo

OK with a total of 5 weeks ((35 days) from one day to one week in duration) camping on the Magnum, I can say that it is worth every penny spent, even with the lack of controller when first purchased. this thing charges like a champ regardless of input voltage/frequency and its inverter function is bottomless. I have worked/thrashed this thing including haridryers, microwave, small A/C and a couple of power tools (electric chainsaw, circular saw and once even a porter cable mini router table.
absolutely no issues with the inverter, or charger portions of this unit. My only suggestion is to double up on all of your wireing standards. it is simple math when wireing 12 or 24 volts have large losses over any length of cable, by doubling your cable sizes you get better performance from your battery bank as well as the inverter. I started with 00 gauge and later swapped out 0000 gauge on the connections to the battery and while the 00 was GTG the 0000 was even better.
Customer Service: I actually emailed Magnum in regards to some questions I had about charging profiles and charging times and they answered me. The initial tech rep was on leave, but within a day a second tech rep contacted me and made several suggestions to my chargeing questions, ( my solar chargeing system is so kick ass that it resets the charger out of bulk and kicks it to float too soon) this was remedied with some adjustments to the solar charger and the magnum. Now the solar keeps all charged for normal use, and if I really use some juice, or if the sun is not shining, the magnum charges it quickly and efficiently.
Short of this unit dying just out of warranty, which I highly doubt, I would rate it 5 stars all day long and reccomend it to anybody who is looking for a solid 2K pure sine wave inverter/charger.

Item was well packed. even USPS could not damage this without realy, really trying. Item is very heavy. compared to brand X+++++x (similiar sixed and capability unit) you will not mount it on a verticle or "overhead" mounting configuation, it just weighs too much for any RV or boat without "real" wood or metal as a mounting surface. Its actual weight is so much that it will require "T" bolts, or normal nuts and bolts to affix it to any surface that is vetical or overhead and then it would be dicey.
connection blocks for A/C input and output are very well constructed using full sized set screw blocks to attach wireing.
I did not like the DC input/output studs as they are so close that you need to be carefull of the orientation of the cables to avoid shorting them. (my install uses the mounting studs as a "tie in point" for the distribution block" s for the rest of the 12 VDC system so I could not use the covers that came with the unit.
My one real complaint: you absolutely have to buy the remote to program the charging system for this unit to match your batteries 14.4 is no longer the reccomended voltage for liquid lead acid deep cycle batteries, many manufactures now suggest 14.7 or 14.8 for proper charging. chargeing the majority of AGM's or Gel cells are also out of the question if you do not buy the remote.
so figure another 200 USD for the remote when you are making your decision.
will update later with more data.
voltage and frequency issues are none existent with the unit. It operates exactly as described in the literature that came with it (as well as online advertising from Magnum) . Testing it out this week end using my home power source (Japanese spec genset (50 or 60 htz selectable 100 volts) shows that the unit will work fine on the lower voltage and odd frequency shifts that occur with foreign power. unit swapped back and forth from shore power to inverter with no issues and properly charged battery bank with no hiccups.
It does use a bit of juice when it is idling not producing power even with the search function on. if you are boondocking and using solar as primary battery charging I suggest that you turn it off when its not needed. I use a samlex 300 PSW inverter for cell phones, laptop and even a small lcd tv.
I only really use the full 2kw when using the microwave and or the A/C. The microwave and the A/c together use right at 2200 watts which is the 30 minute max rating. I never sent the inverter into shutdown, as with A/C running I only ran the microwave for about 15 minutes for some defrost/reheating chores but it did cause the inverter to run up both fans to a higher setting and was pulling about 180 amps or so according to my trimetric.2030.
its efficiency is slightly better than advertised, (subjective as I did not bother to record th total amps used for the xantrex unit that this replaced). I was able to run the a/c by itself for a total of 4 hours (w/no input charging) prior to hitting my personal threshold of 65%. I then plugged into a 100 volt 50 htz 15 amp outlet and was able to charge and run the a/c for about another hour before I tripped the campgrounds breaker for pulling too much juice (20 amp breaker). I shut off the charger portion allowed the shorepower to run the a/c and solar panels recharged the batteries over the next couple of hours.
all in all a grat weekend and I am totally impressed with this Magnum unit. It has so far walked circles around the xantrex that it replaced.
last update will be at the end of the fall camping season beggining of winter camping season. I am a 45+ y/o ski bum also,(read cheap SOB) so winter camping at the resorts parking lots is a requirement of my camper. :)
Because it will be a few more weeks before I can put it in my motor coach permanently
because of the weather. Everything seems to work as described. Bought with the ME-RC50
remote panel. I hooked it up using four T-105 Trojan batteries.
