No fuse good
2000w inverter
- Thread starter Rob jones
- Start date
I use this 2000W 12V Pure Sine Wave Inverter With English Standard Socket its runs a 800w microwave and kettle no problem, it pulls 135amps/1.5kw with the microwave on also has ac passthrough if your on hookup
FWIW....
Renogy recommend a 100ah lithium battery per 1000w of Inverter.
So 200ah ( or 2x 100ah lifepo4) for a 2000w inverter setup.
rough max power draw is 100A per 1000W ( so 200A per 2000w )
that means you need to fit a cable setup that can deal with the max expected power draw..
and over the years i find these rough averages to be correct. (100ah per 1000w and 100A per 1000W)
example Renogy lithium, max discharge is 100A per battery.
so for 2000W you need two of them.

Thanks @Dellmassive, that's what I was thinking and read. I am considering holding out and going for the Roamer under seat option, but it states inverters up to 1500w:

12V 230Ah Seatbase Lithium Battery — Roamer Lithium Batteries
The Seatbase LiFePO4 fits perfectly under a campervan swivel seat. With premium compact cells providing 230Ah of useable capacity and a high power BMS...

yes . . . i think thats because id the 120A max continuous discharge rate.
though it can peak at 240A
so depends on your use case and loads.
what do you want to run?

@Dellmassive for weekend events, kettle, laptop, occasional small heater? Possibly a coffee machine (which I know is a bit of a marmite topic on this forum!).
lol . . . . id be more worried about "a small heater"
any small heater will muller your batteries. either from the inverter or 12v side.
look at gas or derv for heating.
im no expert but i believe that for any electrical heating you will need EHU. - (its just to much of a drain on the 12v system)
even a 800w smaller oil heater running for 10hrs will kill the battery bank.
(ie pulling 80A for 10hrs !!! - you will need 10x 100ah lithium batterys - then 20 hours to recharge them with a 40A charger . . . so either way you will end up using EHU or diesel to replenish the batterys stored energy)
defo best to look at derv heaters.
saying that i do have these 100w and 200w heaters for load testing - they are very effective with a decent fan.

jokes aside - you need to look at a diesel heater for heating
using 12v batteries for heating is never going to end well - too inefficient.
.
barring the "small heater " bit.
the rest will be fine . . .
ie
kettle,
laptop,
coffee machine,
USB chargers
cooler box / fridge
fan for summer
LED lighting
etc etc
Perfect - thanks @Dellmassive. I was just thinking the Roamer undersea was neater and similar cost to two LiFePO4.
Believe the next generation of the Roamer underseat batterys have a continuous discharge rate of 250A.
Just placed an order with Roamer for the gen 2 230ah seat base battery.
They are available on the website for preorder now too.

@BognorMotors - Could you DM me with the details also. I am considering something similar at the moment for my van
@Dellmassive Instead of buying a 1000w invertor is there any harm in buying 2000w but only using under 1000w products till I buy and fit a second battery?
No problem at all. It’s all about power in/out, not the rating of the inverter.
No that's fine..
If you install cables and fuses for a 1000w setup, then make sure you don't pull over 1000w.(100A supply)
.
But ideally you should install the 2000w cable and fuse setup from the off ..... (200A supply).
You can pull above 1000W, from the inverter..... It will just try and pull the current from the battery, upto either the max the battery can deliver...
Some 100ah lifepo4 batterys have a 100A or 150A max discharge rate..... That's the limiting factor.
Plus overall capacity.
The trick is to place the I inverter as close to the battery As possible, to keep the DC cables as short as possible.
And always fuse the battery connection.
Brilliant thanks. I have ordered the 2000w renogy inverter on eBay with 15% off. I believe my battery is 90A.
Is there a particular fuse connection you would recommend?
Solar panels are working well so thanks for the advice with that too.
Next job lithium batteries…

@Sim73 yes.
You need to follow the insall guide.
The 2000w needs BIG power.
So you will be looking at fat cable and big fuses.
2000w at 12v is about 180A, so you will be looking at 200A ANL, MIDI or MEGA fuses.
The 2000w inverter come with two red and two black cables, that's to double up, so instead of one super fat cable you have two thinner ones.
Black cable direct to chassis.
And red via a fuse to the battery bank POS.

On a beach in Indonesia no doubt, makes it Fair Trade as well then
@Dellmassive In terms of batteries would you recommend this for my setup? 12V 230Ah Seatbase Lithium Battery — Roamer Lithium Batteries
I assume I cannot fit two separate batteries under the drivers seat and my double passenger seats swivels and is used for storage.
