Hey guys, I am trying to identify a "good" 12 volt inverter system for continuous use. I am beginning to look like the back room of a 1970s Radio Shack. I need to cover 2 applications, 1 1000 watt continuous load (with an occasional 1500 watt motor), and one smaller <500 watt continuous load. The battery bank for the 1000 watt load is 1000ah 12 V, and the battery bank for the smaller load is only 200ah 12Vs, both battery banks are charged by solar arrays.
The small load (currently a 20 watt bug zapper) has killed a couple of cheep 1000 watt modified sine inverters
The larger load (~900 watts led lights) killed a high end 1200 watt inverter (AIMs with transfer switch), a 2000 watt modified sine inverter (harbor freight), and Renogy 1000 watt pure sine unit.
The inverters on the small load last about a week then just go into alarm mode... I hate to have to put a big inverter to run a very small load.
Currently, I am trying to figure out what to replace this one with. (it died yesterday)
The inverters on the larger load have had a number of failure mechanisms, but usually it appears to be an internal short resulting in an overload condition. These units have been lasting between 2 weeks and 6 months. The AIMS lasted the longest followed by the harbor freight.
Right now I am running a SUDOKEJI 2500W Power Inverter 12V DC to AC 110V/120V (2500 watt modified sine/ w remote) but is has only been in service for 10 days.... time will tell.
Anyway, what I really need is a RELIABLE inverter that can handle constant loads (like a SHTF event) for an extended period of time (Years would be good). If any one has any good experience with an inverter (brand and model) that has performed well under continuous service for over 6 months, I would love to hear about it.
