240V cable failure


240V charging cable failed after approx 12 months. Seems to be a common problem. 12V still working but is a real pain as I would prefer to leave it on charge in the garage. Ark Pak people didn't seem to be very interested as it was out of warranty. Sent many messages via email to Arc Corp, with no reply from them.

Disappointing 730


I bought the AP730 as I wanted to have the best. I saved to get this unit. I took it camping for the 1st time and it was amazing.. my solar panels charged it up through the day and ran my engel for the total duration of our trip at zero degrees. Charged up phones etc..
Went to take it on the second trip a few months later I unplugged it from the wall and the screen went blank. I noticed the 10amp and 30amp fuses had blown. I replaced them and once the inverter was switched on the 30 amp would blow again. Emailed Arkcorp I'm still waiting for their reply/help.. that was 2 weeks ago now!!
Great product but way too expensive to use once!
Customer care ZERO.

If it's when charging, check the inline due for the car charger or the AC charger might be busted.

Car charging also depends of the plus your hooking into.


I too have this problem on my mate's Arkpak 730 it also says Alarm Low Input Voltage when trying to charge both with Car charger and Wall charger. I happen to have the same Arkpak 730 with my own chargers and battery. We tested his battery and all of his chargers with my Arkpak and no issue - suggesting he has a problem with the charging mechanism in his ArkPak. I'm curious to know if the alternatively badged battery boxes might have a similar issue (Engel Smart Battery Box Series 2 or Thunder Weekender) or if anyone out there with those boxes experiences a similar error ?


Had a chat with ArkPak guys and found that the issue was a melted and worn connector on the inside. Even though it says warning do not open - the gear inside once you open the lid (4 screws) is easily modular and accessible and the suggestion to do this and repair this connector was given by one of the ArkPak guys themselves. I went to JayCar and bought a plastic crimp on connector and replaced the one inside that was a bit burnt and worn and all was good after that - has been working well.
