Default Roadtrek CS Adventurous: replace inverter/charger advice

2014 Roadtrek CS Adventurous. Inverter is failing - looks like control switch panel is failing. Woudl like to do a direct swop with same unit - so its an easy swop out / swop in. Having trouble sourcing the original unit. The original factory inverter/charger is 3KW unit from Microgreen Model MG-CI-AXA-3000-12-DC1 1420. This is a "badged" unit from China. Microgreen no longer supply it. The other label on the unit has this info: Model No: LW3000W-12-C, Input: 120VAC, 60Hz, Output: 120VAC, 60Hz, Barcode ||, 12302-14051470025.
It looks very similar to this unit, both specs and visually: https://zlpower.en.made-in-china.com...ter-1-6kw.html

Does anyone have advice on how to find one of these units?
Many thanks

Yours looks pretty similar to the Renogy model below. Very expensive, however. You can probably find a similar model on Amazon for cheaper (maybe re-branded, but basically a similar unit0. Just make sure the dimensions are the same or smaller. so it fits. Most should hardwire in the same way as your old one.

One additional consideration. If you think you'll ever upgrade to Lithium batteries, you should consider an inverter-charger with a lithium-compatable charging program.

Thank you. Good info. Indeed the new RoadTrek supplier, KS2Corp is offering LiI chargers. I still have AGM, so your idea of having both is good. Thanks for the Renogy info - & I'll do some sleuthing on Amazon and EBay as well...

Mark C,
What are the symptoms of your failing I/C ? I have a 2015 CS Adv. with a Microgreen I/C very similar to yours. Mine may be failing too.

Symptoms - erratic. When on shore power, cycling off sporadically. LEDs cycling with bleeping. Staying OFF even when switch is ON (with power mode OFF). Would restart if tapped on side of unit. Then misbehave sometime after. These symptoms got worse to the point the inverter was hard to power on at all. It has been a long process to identify an available unit with same form factor, wiring layout & remote - although there are several (e.g Renogy and Microgreen). I am awaiting a new 4,000W unit from Sungoldpower. My opinion is these units are all very similar, all from China and out of date compared to latest units (that support LiI batteries, have better sensing). But they fit that slot behind the back seat...

Mark_C,
Thanks for your quick reply.

I've seen that unit on Amazon. There's also a unit from Aims there too. My Microgreen only has one symptom, so it's' not quite as frustrating as yours. I'm still not even sure the issue is with the Inverter/Charger.

When on 30 amp shore power, I get power interruption whenever I draw about 16 amps or more.

The way I am alerted to this interruption is by the sound of the Start-Up chime of the Microwave. Not USING the microwave, just its re-starting after power has been interrupted.

Example: While running the Alde heating on Level 1 of 2 (about 8 amp draw), then trying to boil water in an electric kettle (about 8 amp draw), the AC power (and ONLY AC power) is interrupted. I know this by hearing the kettle click off, followed by the microwave start-up chime.

No error codes on the I/C and no changes to its display as the interruption occurs. This has occurred at multiple campgrounds/power pedestals over multiple months.

If anyone has suggestions on what to check, I'm grateful, as I've been trouble shooting this for a while now.

Obviously the internal transfer switch. I would start by checking, tightening the AC power connections to the inverter then take the cover off and follow it to the transfer switch looking for evidence of high current heat.

Maybe you can replace the transfer switch.

I will give the connections a look and attempt to tighten them. If they’re OK, I’ll then think about removing the unit from the van and taking it apart. Thanks for your time and expertise!

Hi Folks,

I had the same unit in my 2018 RT CS Adventurous. It was less than 1 month old when it all but caught on fire! Overheated to the point where it melted the connectors and filled the coach with smoke!

I contacted davy.hung@microgreen.ca at Microgreen. He was very helpful. The unit that malfunctioned is no longer available as "new", however it was (in October 2019) available as "reconditioned". Microgreen did have a new replacement unit, however it is several inches longer. In spite of the additional length it did fit in the allocated space. The swap was quite easy. The worst issue being removal and replacement of the sofa bed.

My unit was equipped with 2 - 200amp lithium batteries. The new inverter worked flawlessly.

The replacement unit model number is MPIC-LF30121. I believe the retail cost is approx. $800 USD plus shipping from Canada at $150. Mr. Hung was kind enough to sell me the new unit for $550 USD plus shipping due to the age of my unit. It should have been covered under warranty, but Microgreen wouldn't honor the warranty due the the RT bankruptcy. They said they were stuck for megga bucks!

Hope this helps.
