1000w Renogy inverter question

[NicolasH]

We’ve recently installed a Fogstar 105ah lithium battery and I’m already really impressed.

I was thinking about fitting a 1000w Renogy inverter but was wondering what this could power in the real world and for how long. Does anyone have this inverter (or similar) and could give me some examples. Or is our battery capacity simply too small to power anything useful.

Also, was does the collective think of this inverter.

Thanks.

That battery is perfectly matched for a 1000w inverter.

How long it lasts will depend on whats plugged in.

Quick maths.

1000w 1hr
100w 10hr
10w 100hr


I also run the 1000w Renogy on a 230ah Fogstar.

Thanks Lee, I’m really tempted to buy one.

I have an inverter which came with the van, it's a Antares/Cotek 750w... is this any use for "off-grid" use, or would I need something with higher power?

 

[Pauly]

It has no relevance or suitability factor to off grid use, if anything a higher powered invertor will be worse for off grid as you will empty the battery quicker

If thinking about off grid use then the single most important factor is recharging the battery and replacing the energy you consume, no point having an invertor (among other things) without adequate means to recharge after use

Ok I will re-phrase the question...

Is a 750w inverter enough to power things such as an airfryer / kettle / heater?

No...

All those are now preset hungry.

I'll place the inverter in the bin

We have the 1000w inverter, we like it as it’s not too big, the bigger the inverter, the bigger the battery, then the bigger all the appliances might get.. we use it mainly for electric blanket , hot chocolate machine, slow cooker, mini air fryer, Vango induction hob, etc, not all at the same time though ..have a 160 battery which is not too big, definitely useful to have if you have room, they are not expensive

Which mini air fryer & slow cooker do you use please? I was wondering whether the 1000W renogy inverter would be enough for me to go gas-less with a 160AH Lithium battery.

Roamer 230Ah seatbase battery and 2kW Renogy inverter.
Picture one is a mains 2 slice electric toaster...

That's 776 watts at 12.7V so drawing just over 60A of leisure battery power.
Picture two is a tiny mains "1kw" travel kettle...

That's actually 943 watts at 12.7V and drawing 74A from the leisure battery.
As @Pauly said you need to be able to bung electric into the leisure battery as part of the system, a B2B charger is a given so the battery is charged when driving, a standalone lithium profile charger is a bit of a luxury backup, I've used mine once but with picture three solar panels for free electric are a no brainer...

That's purely solar input on top of the fridge pulling power out so still nearly 20A of power going into the leisure battery from a couple of 175 watt Renogy flexy panels on the poptop, yes I know free is a bit optimistic especially when you upgrade inverters or blow stuff up plus one flexy panel making a bid for freedom when going to France last year but you get the idea.

Cosori 2L mini 800w, it is fine for heating up a pasty etc, but being a low power will take longer to heat things up than a more powerful one, can’t remember slow cooker, but they are all low power, we have a double gas hob and also the EHU if we need it, so covered for many different types of outings in the van, I don’t think I would go electric only with a 160 battery, unless you had a portable gas stove for back up, we carry one of those too for cooking the sausages and bacon outside the van..

Yes, tested the 700w Vango "Sizzler" in the house and it took 10 mins to boil 1 litre, but only used 6-7 amps, so appreciate these low wattage devices are slow. Thanks. I think I will leave the gas in for now. Fit a 1500W inverter and see how I get on. I need a better understanding of what both my power and energy needs and supply are to assess if all year round 160ah reserve is up to it.

Running 240v heating devices off grid really makes you appreciate what sort of energy we just draw from the grid without a thought
