I'm just realizing I should install a combiner box at the solar panels. I'm planning six 300 watt panels at 24v. Each panel generates 12.5 amps, so six 15 amp breakers in the Midnite Solar MNPV6 combiner box?

This thread has been helpful. I'm having a similar issue. System is a conext SW 4024, four 12v Kilovault AGM batteries - 2 series in parallel for 24v. Total 360 Ah. Midnite Classic 150 with 6 Q cells- total of about 2500 watts solar at 48v. New system installed June of this year...

Looks like the Whiz Bang Jr is the best overall solution. I like my Classic 150. The WBJ will eliminate all the guess work in trying to understand the state of my battery bank. I had seen this product in the past, but never understood what it was for. Wish I had known earlier as it would...

My application is an off-grid home in Montana. 2500 watts solar panels; Conext SW 4024 inverter; Classic 150 solar charge controller. Batteries are four AGM 12v 180 Ah - two series pair in parallel for 24v, 360 Ah. The AGM's are near end of life and I'm strongly considering LifePo. I want to...

Still working this issue. Kilovault seems to be suggesting that the poor battery performance is entirely temperature related. I can't believe that having the batteries at 40 degrees below nominal temp of 77 should result in a 90 to 95 percent reduction in the ability to hold charge. I'm...

Thanks I have the manual and have poured over it. It is pretty vague on temperature effects on charging/discharging. The only chart is Figure 7 in Section 4.2.2 the vertical axis is time and the horizontal axis is temp. This doesn't explain to me why the batteries instantly drop to 80% upon...

The Primus turbines have an internal charge controller, so they hook up to the battery. You do need a stop switch, breaker and ammeter in line between the turbine and batteries. The turbines will apply the electromagnetic break under two conditions: when the batteries reach full charge (to...

Any opinions about the SunGoldPower brand? This unit will do everything (it claims) at a killer price: https://sungoldpower.com/collections/pure-sine-inverter-charger/products/4000w-peak-12000w-dc-24v-split-pure-sine-wave-inverter-with-charger#specification_1

Thanks Steve: That helps. My generator feeds 240v into the Conext SW inverter. Running on propane, that "30 amp" outlet only delivers 19 amps max. AC. I just need to set the inverter/charger parameters correctly. If I'm understanding correctly, the standard charge rate is 30 amp per...

some more notes: last week I tore the battery bank apart and relocated it to the other side of the wall where I can insulate it better in an attempt to raise the temperature. At that time I checked the voltage of each separate battery. Within an hour of taking them off a five hour full sun...

Current setup is lead acid AGM. I'm about to install LifePo - of course, settings will have to change.

What I keep coming back to is that I believe the Kilovault batteries were damaged. The system went live the end of June 2021. Everything was great - then short, cloudy winter days came along and I needed to start using the generator to supplement. I carefully checked all the settings based on...

I did not have this updated manual. Thanks for that. I have an old Windows 7 laptop. I bought a netgear N300 wifi router, model WNR2000v5, one of the ones listed in the Status Panel software manual - attached here. With Midnite Solar tech support on the phone, we couldn't get the laptop to...

I've looked at the manuals for the Schneider, Outback and Magnum units listed above and what I don't understand is why the need for an "inverter load panel"? I want my main service panel to be the inverter load panel and forget about the Grid source. I'm not paying the $5000+ to extend grid...

Thanks for the detailed reply, but to be honest, this is all over my head. I just ordered a pair of 24v 100Ah Chins LifePo batteries. They each have their own BMS. I'm not a technical guy and don't have the knowledge background, time or money to get into the detailed testing and tweaking...

Not sure if you have resolved this issue or not. Just found your thread. I have the same batteries and they are close to dead after 18 months. There is a typo in the installation and user manual for the temperature compensation variable. Section 4.1.2 shows the value as you state above...

Still experimenting with the Conext SW 4024 charger settings for my new LifePo batteries. 2 Chins 24v 100 Ah in parallel. Max charge current per battery of 50 amps. My AC power is supplied by a 4500 running watt generator that can only supply 19 amps on propane. Yes, I know now that this is...

I am installing two 24v 100 Ah Chins LifePo batteries to replace an AGM battery bank. Each battery has its own internal BMS, but are not smart batteries (no blue tooth). I am connecting these to the e-panel with bus bars (rather than daisy chaining). I've been watching some videos about the...

I'm setting up a solar system and will power a 100 amp residential service panel through a transfer switch. I'm looking for the right 24v DC inverter (about 3000 watt pure sine wave) for this application. The output needs to be capable of being hardwired. Doesn't seem to be a lot of choices...

Wow. You have a LOT of Ah's. My lead acid (which are going away) only has 360 Ah (rated) times 50% at best - which I never really got since they were damaged by overcharging until the fourth tech support was able to find the problem with the inverter/charger temperature correction setting...

I have two 100 Ah 4 volt Chins LifePo batteries and need to charge them safely from my Conext SW 4024 inverter. Each battery is rated for maximum continuous charging current of 50 amps. They are connected in parallel via bus bars. Do I set my inverter charge setting to 100 amps max? (I really...

Thanks. This is good information. In the Chins, the only battery they seem to offer right now in 24 volt is a 100Ah (the 14v, 200Ah is out of stock), so I need two of those in parallel to get 200Ah. For the pump, it is a shallow well 1/2 HP 240 v pump (in a cistern - head is only about 8 feet)...

Thanks. My strong suspicion is that these batteries were damaged during several weeks of overcharging before the vendor tech support, the battery manufacturer tech support and the inverter tech support could come up with the correct value for temperature compensation by the inverter. Ever...

Thanks This was really helpful. The reason I'm going to LifePo is that the 380Ah of Lead Acid should be adequate, but is NOT. My solar array is barely sufficient to fully charge the batteries in the best of conditions: Long sunny days in July. With these short winter days, the batteries never...

Wow. Good information. I feel like I'm getting in over my head with some of the details. I'll have the help of an electrical engineer when it comes time for installation. I've already ordered an Epever MPPT 80 amp charge controller. Are there any issues of compatibility with Midnight Solar's...

I have plenty of charging capacity in my panels. That's never been an issue. My problem has always been charging capacity through the conext inverter/charger when on AC power. My generator is undersized for one thing, and then the conext is limited to 90 amps of charging, which really isn't...

Kilovault claims the following in their advertising: -Super-Fast Charging - High charge rates allow the 2100 PLC to go from 50% up to 90% state of charge in under an hour. -Partial State of Charge Applications - Pure lead + carbon = greater cycle life in both PSoC and non-PSoC off-grid...

Thanks for the chance to clarify. I'm in North America. A standard 100 amp service panel is designed for 240 input - split phase - so that each side of the panel is 120. This allows for an appliance or pump breaker spanning both sides to deliver 240 to a device. Not that I want to, since I'm...

Despite the affordable cost, I veered away from the SunGoldPower inverter. I was frustrated that I could not determine for sure from the documentation if it is a true split phase 240v and not a European style 240v. I.E., three conducter plus ground or only 2 conducter plus ground. Then, when...

I have four Kilovault 180Ah AGM 12v batteries - two strings of 2 for 24 volts. I've been running them for about 9 months. Decided it might be good to add a battery balancer, so ordered the KiloVault BE24 balancer - one unit. Instructions come with the caution to charge the batteries to the...
