Hello from South Carolina

There is nothing wrong with using an oversized inverter. One reason would be to allow for future expansion. Just don't draw more power than your current battery system can handle.

Very informative. I have a 100Ah AGM Lead Acid and a 120Ah AGM lead Acid batteries. My Invertor (MUST Invertor) is rated as 12V/1000W. I have an MPPT charge Controller rated as 150 MaxPVoc. What will be my set up?

Connecting the batteries in parallel is best. However, that's insufficient to run a full 1,000W load on it. It will work, but as I said in the video, it's not healthy for your battery.

I've been using four sealed lead acid batteries with a 2000 watt 12V inverter powering washing machine that peak draw about 1800 watts. Been in service over one year now. I do 2-3 loads per week. So I'm apparently way under sized my battery bank?? Thank you for good informational video.

Not enough solar to recharge the batteries. It depends on your load. Make a calculation and see how much you need. Checkout my video about sizing a solar system.

I have 4x 48v 100ah rack batteries and a 5600 watt inverter.. I'll be buying another 4x batteries and also updating the inverter to 8 or 10kw. That's hybrid inverter/charger.. And 12-14 270w panels.. I use MPP inverter/chargers. They are good but have a higher standby current draw

Great video. I love your animated pen technique... question: You suggest a fuse per battery prior to connecting to the bus in a parallel setup. The lithium batteries I use have a solid 200a BMS which shuts off with a short or other over-current situation. Is an MRBF fuse on each battery necessary? (the after-bus-bar [positive line does have a 200a fuse).

@cleversolarpower

The BMS cannot disconnect a short circuit (high ICC) because it's an electronic switch. It's best practice to fuse every battery. Checkout nh00 fuses, they are quite cheap.

Hi, Nick. I just came across your channel the other day and have learned a lot already after watching just a few of you tutorials. One thing that I learned... I have been making some very wrong assumptions about size and capacity. On my RV I currently have 2 - 100W solar panels, 2 -125 AH AGM batteries, all wired in parallel. I have them connected to a 40 amp EPever charge controller and to a 2500 W Sunforce Pure sine wave inverter. Problem... this set up will not run my microwave or coffee maker without tripping the cut-off circuit in the inverter. I have recently acquired two 300 AH Renogy Lifepo4 batteries, not yet installed. Will this solve the issue with tripping the inverter or am I missing something altogether? And do I need to resize my inverter to take the new batteries? Your comment or those from other followers of your channel will be greatly appreciated. Thanks.

Hello Trevor, answered your email.

I have two 12v 120ah lifepo4 on 3000watt 24v inverter. My charge controller shutdown. I also have four 250 watt panels connected in parallel.

How does Gel batteries fit into this math ?

I have a Renogy 2000w Inverter with two Eco-Worthy 12.8v 100Ah lithium batteries in series. Am I properly sized?

@cleversolarpower

2 ай бұрын

2000W/12V=166A/0.9=185A max draw from inverter. A 100Ah battery can deliver 100A, so 100A x 2batteries = 200A. So you are properly sized.

2x12V100Ah in series and a 24V 1500W Inverter, was this the right move? I'm about to buy solar panels hence I found your channel and I'm amiss as to whether the same efficiency is used for Sealed Lead Acid vs Tubular Lead Acid for I was under the impression the latter shouldn't be allowed to discharge less than 50%? Should I opt to get a smaller inverter?

@cleversolarpower

22 күн бұрын

This will work. Every battery can deliver a max of 100A. Since they are placed in series, this is the max then can deliver, so each battery 50A. 1500W/24V=63A -> correctly sized.

I have a Sungoldpower 4000w 12v inverter/charger in my rv with a LifePo4 12v 300ah battery. Is that too much inverter? I am adding another 12v 300ah LifePo4 battery in parallel for 600ah if that helps.

I don't recommend going over 2200W for a 12V system. Your wires will be costly. Check my video about 12V,24V or 48V battery systems.

I just ordered a 500W Bestek inverter to get myself acquainted with using inverters as an alternate power source. So in theory, 12V 50ah Lithium Battery suffices for 500W inverter based on calcs ... but do you still recommend a 12v 100ah lithium battery and, if so, why?...Without doing the calcs, it seems i can potentially get longer usage with the 12v 100a battery on a 500W inverter before recharging, but I would like to know your thoughts? I don't intend to max the load at one time, so my usage at this state in learning to use inverters would be light intermittent use (i.e a lamp periodically, charging my lap top periodically, charging phones , and maybe running my wifi for short intervals).

Of course, having a larger battery will make the fridge run longer, but it would also take longer to charge back up. I recommend getting the 12V 100ah battery, the price difference is not that much, about $250.

You have a 12V 60Ah battery. At 1C, you can pull 60A max. Assuming the BMS is rated at 1C as well. 650W/12V=54A. So you can run a 650W load.

More batteries is better (most of the time). You got to see that the system is still properly sized. Batteries should have 3 days of autonomy. So if your daily consumption is 800Wh, then you don't need an extra battery. You can charge the batteries with 2A, the charging current doesn't matter that much, it just impacts charging time.
