I just got off the phone with Signature Solar and they're telling me that I can't discharge and charge the EG4 Lifepower battery simultaneously. Please tell me this is a mistake. Now I'm trying to understand what I'm supposed to do for power while the battery is charging? I'm really confused...

I placed an order for solar panels, battery and charger (chargeverter) on Jan. 7. I was told the chargeverter would be in stock middle of the month. Got the solar panels in a week. I was also told they were moving warehouses so it would be about a week before the battery would ship. Here it is...

The only one I can find (on amazon) won't get here for a month or more. I've found a few other 20a but they are 32v max. Any other sources? Thanks.

I'm using the design in this pic as a model. But I don't really see the value in having a circuit breaker between the CC and the fuse. Seems redundant to me. Am I right? Thanks!

I'm realizing how much money energy efficient appliances (esp. fan & air purifier) will save me on the build out of my solar system. Are energy star rated appliances about the best out there? Thanks!

I assume that if my entire 48V system is wired with 12 ga wire and my largest component is a 20A CC, the main fuse (see pic) should be 20A. Is that correct? Thx!

So if your wire supports 20A (12ga) but you have a 10A inverter, the fuse should be 25-30A correct?

I've got a 10A 48V inverter but I'm using 12 ga wire for my entire system. Does this mean a 20A battery fuse would be best? If not, how do you size the battery fuse? Thanks!

This is a tiny 48V system. The reason I went with 48V is I have a gas gen and am getting the chargeverter for backup. See attached photo for components and let me know what's wrong (if anything) with my fuses and wire sizes. 500 watt inverter @ 48V = 10A = 14 ga wire & 15A fuse 20A charge...

Is it the distance from your panels to your charge controller or double that? Thanks.

I've got 3 strings of 4-100 watt panels in series. Not sure I understand when fuses are ok and when a combiner box is needed instead. Any insight is appreciated.

Here's the numbers I came up with for my new 48V system: 4 - 100w panels in series: 18.5V (VMP) x 4 = 74 V @ -12 deg C = 86.4V 3 parallel strings: 5.41A (IMP) x 3 = 16.23A x 1.25 = 20.29 A 86.4V x 20.29A = 1753W panels are 60 ft from controller 20.29 amps @ 60 ft circuit = 8 awg wire?

I've watched @Will Prowse 's DIY 24V system from scratch but all of the 48V systems are using all in one setups. The main reason I want to do a 48V system is I already have the gen for charging the 48V configuration with a chargeverter. Is there any difference in the design of a DIY 48V system...

I just placed an order with Signature Solar. After getting the confirmation, I noticed two problems with the order. So I called and was hoping to leave a message to cancel the order so I can redo it but there is no voicemail. Now I have to call back or send an email which just wastes my time...

The IMP of the panels is 5.37 & 5.41 and the VOC is 22.6 & 23.1. I was told since those numbers are close, its ok to mix these in a series string. Is that correct? Thanks.

I need a 500 watt pure sine inverter and a 20 amp controller with 1k panels and a 5k battery. Is this doable in 48V? The main reason I want to do 48V is I already have a 6k generator and want to get the chargeverter for backup. Having a hard time finding small components in 48V. Thanks!

Looking for a high quality propane gen to charge my 5k battery. I want one that's not disposable (ie parts need to be available). Thanks!

I have complained and I see a lot of other people complaining about customer service. And now I know why. Have you noticed that the companies that offer high quality products and excellent service are way higher in price than the Bluetti's, Signature Solar's and LiTime's of the world? Look at...

These seem like a really good value for $1000. About half the price of SOK batteries per watt. I'd like to hear some reviews before buying though. Anyone?

Q6: If I replace the included MPPT module for a batteries expansion, how much solar input can I use when the EB240 is unhooked from the expansion batteries and is in stand-alone mode? A: The EB240 could have a maximum of 500W from solar panels without MPPT module. You should set panels of 400W...

My little gas generator only has one output @ 700 watts. Can I put a splitter on that outlet and charge 2 solar generators @ 350 watts each? Thanks.

I've got 2 Bluetti EB240's. One won't charge and the other has no AC output. Bluetti is being impossible about servicing the one that is under warranty so I sure as hell won't send them the other one. The question is what can I salvage from these units if anything? I assume the batteries should...

I've been trying to get service on my Bluetti EB240 for 5 months. I provided a copy of my credit card statement showing the payment to them but they continue to make excuses like "we can't find your order info" and the one attached. This company is just plain crooked IMO.

Yea, this is slightly off topic. Hopefully thats not a problem. I've got a 1 1/2 hp 240V Goulds well pump that's rated at 2000 running watts that would be way too expensive to try and run on solar. I know startup watts is going to be way more but I don't find that info in the specs. I need to...

I found this chart in another post but I'm a bit confused by the "critical vs non-critical" columns. I assume a laptop would both fall under the critical column. My panels are 150' from my 12V solar generator and with 400 watts of panels I'll be generating 33 amps so according to this chart I'll...

I've got a Bluetti EB240 2400 watt solar generator. I've got an upgraded charging brick that will handle 500 watts but I assume I can't just plug that into a generator and need to buy a charger made for this purpose. How do I go about finding the right charger? Thanks.

If I need 400 ah of batts, what are the advantages & disadvantages of going with 4 - 100 ah batts or 1 - 400 ah batt other than having to physically hook multiple batts together? Seems like having 4 would be better from the perspective of a failure. If one fails, you still have 3. Thanks for any...

Man this stuff gets confusing. I swear I saw one of Will's videos where he said you can't use 12V panels in a 24V system and then I also saw that if you are using 12V panels in a 24V system, you have to put them in series to get 40V minimum? Which is it? And does the same rule apply to...

Will's generic formula is divide your total battery watts by 5 and this is how many watts of panels you should have. The idea being that you should be able to charge your batts in one full sunny day. So if I have 5000 watts of batteries, then 1000 watts of panels should do it right? But in late...

I'm trying to figure out how many watts I will save by using a 12V fan vs a 110V. For a fan that produces the same cfm, is it just the power to run the inverter for the 110V that you will save or are 12V more efficient in general? Thanks for any insights!

My EB240 will support input of 500W and 68V OCV. If I put 5 100 watt 12V panels in series, in full sun I get about 300 watts input into the EB200. Does this mean I can add more panels until I get to 500W or is the voltage already maxed out w/5 panels? I just don't know if the lower watts means...

Who's a reliable and reasonable vendor that offers good service and stands behind their products?

Is it true my Bluetti EB240 can't be used while its charging? So every time it needs to be charged I'm going without power for 5 hours minimum? Makes no sense. Am I missing something? I never would have bought it had I known.

The more I read about both technical and customer service issues, the more worried I get about spending another $4k on a solar generator. Seems like all the big names like Bluetti, Delta, etc. have terrible service. I already spent $2k on two bluetti EB240 systems 2 years ago and neither work...
