Regarding measurement of parasitic 'off' load from the EB70 while it's waiting to be turned on (since the battery can't be isolated), I fully charged it, left it for a month (4 weeks to the day), and to top the battery off, it only pulled 1 watt hour from the mains, so I can confidently say it...

I've decided to get a 12v DC E27 lamp (ebay 363861186585) and a constant current / constant voltage module (ebay 354644927748) for a dimmable light. I will put the module in its own box, give it a DC input socket and replace the constant current trimpot with a panel mount one (ebay...

What's its efficiency and no-load wattage like?

I'm thinking of getting a Victron Phoenix 24v 500VA for ~ $250 AUD.

What did it cost?

Hi all I bought a "KRXNY" brand 24v 3500w inverter and it works fine. I'm thinking of buying the 500w equivalent: https://www.ebay.com.au/itm/113636746545 to power a constant load of ~95 watts 0.6 amps (~0.6 power factor). I'm wondering if its fan is likely to run (hopefully not at all) with...

I guess it shouldn't make any difference with these small amounts of power, but is it a split phase inverter? This came to mind when I was reading this thread: https://diysolarforum.com/threads/solar-inverter-led-lights-flickering-while-running-the-washing-machine-or-blender.53046/

https://www.ebay.com.au/itm/195027637555 Hopefully these would last. $55 "(Module)SSR-20WA-R (1KW) Single-Phase Two-Phase Motor Soft Starter Aluminum"

For those who have the time: https://www.siliconchip.com.au/Issue/2012/July/Soft+Starter+For+Power+Tools This uses a 10 ohm NTC instead of an outright resistor. I noticed that "soft starter" on ebay has some ~$375 chinese units (I don't know anything about these.)...

Contrary to the suggestion of my previous comment, a soft-starter could be automatic if put in-line before the motor. I guess: inverter > timer > soft starter > motor. Hopefully the inverter can cope with it as is.

https://diysolarforum.com/threads/ground-neutral-bonding-the-inverter-gfci-question.43849/ The video in this linked thread shows that grounding the output made the 'low voltage' battery in fact high voltage, capable of pushing plenty of current, creating a situation where there would in fact...

Don't suppose it is started manually every time it starts? If so, might get away with an inverter that soft-starts when it starts up. A spare variac might be handy for a short term solution? Don't know if you can still get the soft-start kits that put the load through a 10-15 ohm resistor for...

What sort of loads will it be driving?

So I bought the 24v version of this KRXNY 3500w inverter: https://www.ebay.com.au/itm/114690705567 I'm wondering if anyone else has any experience to share regarding this particular model? It ran a 1950w heatgun for an hour (then batteries were flat) no problem. It hardly got warm at all. From...
