Lets start from the beginning... When you take the unit out the box, by default, the grid feedback is DISABLED (It operates exactly like a PIP unit). You can connect Grid/Utility power into it (If you wish/ Optional) or it can operate completely off-grid. If its in your camper, etc , Just...

Good Morning. this is in fact the same model that can be paralleled to 8 units, we have made extensive firmware updates and features to the vanilla model you see online. We have been running these Indoors, outdoors, as EV chargers, Welding and Plasma Cutting Operations, Compressors, Motors...

Yes, Im sorry, we offered a special , and got wrapped over the knuckles for it from the supplier, and now from the customers. Usually the PYTES batteries ship just fine with Fedex Ground, so we thought we would try the same method with the SOKs - Ground is 1/3 of the price of freight, but now...

This device has Anti Islanding as a industry standard , so in the case of a power failure - it would not feed back.

If you have a charge controller that is designed for 48V 24V and 12V (auto sensing) , and you have high PV input, and the battery may be 24V as is in your case, and the battery goes open circuit, the auto sensing is going to think that perhaps these are 48V batteries. 1) Battery...

True, but some car battery chargers are designed the same way, they need some sense of what the battery voltage of the battery is before it starts charging it. For example, If I connect a 12V battery to a 24V charger and bump it with 40A, this is a recipe for a disaster, it will cook that 12V...

You can remove the ground N bonding screw on the PCB as shown in this video.... To magically make it into a US "version" and call it by a US suffix. (Just like the 5000ES. After your remove the bonding screw you can rename it the 8048max-US , who know one little screw had so much power?) The...

This is an easy one to fix, your low battery cutoff voltage is set way too low, as well as the low voltage cutoff to switch over to utility. Whats happening is that your battery is draining before the safety limits can kick in. Yeah I know this sounds weird, but if you dont have a battery...

P.S. usa-mpp-solar is not charging sales Tax - YET, plus its free shipping.

Its not perplexing at all, the internal circuitry and CPU needs a specific voltage (and current) before charging can occur. Battery Open circuit voltage does not count, for example your TV remote batteries when they die, you can pull them out and still read 1.5V per cell, but put any load on...

download all the software you want from https://usa-mpp-solar.com/manuals/software. This unit uses "WatchPower" software, the Hybrid LV2424 is the only model that uses "SolarPower" software All the best Ian

You wont find any instructions, because there arent any. :) Here is the deal. a) Your Wind turbine needs to give DC output b) Your wind turbine needs to output more than 30V DC before it can even start to charge the battery, and be less than 115V, to be within working voltage range. c) If a)...

Hello Guys. Let me try to simplify. Both units when connecting inverters in parralel need to be on the same battery. LV2424 - Current sharing cables are only connected to inverters working on the same phase. (any parallel hookup requires signal cables - 15pin DB connector) LV5048 - adding more...

Chuck, we replaced the mainboard with a brand new mainboard. We found it very strange indeed that the battery terminal inputs had gone short circuit, never had one like this before, the fact that it happened again is rather strange indeed We dont have an email or a phone number for you on...

Wired as Off grid should be just fine, (with or without grid assist), others comments welcome. UL listing is planned for this year

Yes it will save its settings, power failure does not matter, you can connect as many watts of Solar your heart desires, but the units can only draw what the battery charging current is set to in the settings. Adding more than 500W solar will just give you 500W max charging power for longer as...

If there is cable and terminal space available, I would double up with the 4/0, its easier to work with two smaller cables than one fat one that wont bend. The cable I have been using is that is easy to work with is. Been using it for years, and then of course, good quality Lugs, with a good...

Another note, when you are connecting those two LV2424s in parallel, if you are just doing it single phase, 120V, then single phase AC input will be fine for both. However, if you are connecting them up in Split phase, note that the only time you will get 240V split phase out, is when the...

Hello. Panel voltage over 115Vdc will lead to NO CHARGE-ing, as the spec says that the voltage needs to be within 30 to 115V (Vmp ) for the 24V battery system 60V is the min for 48V systems (over 145VDC - Voc causes damage) 3 to 4 panels in series would be perfect, and add parallel strings...

Both email addresses are functional as you show above. Did that replacement work ? Now if you had bought your inverter from TW, there would be hardly any support.

60 to 115V is the operating Solar Panel voltage range 145V is the max before damage occurs. 115V to 145V - No Charging occurs - dead zone Page 9 of the manual, (PV Array MPPT Voltage Range 60~115Vdc ) The statement "MPPT is 2x 80amp input. " is not correct, it is 2 x 80A OUTPUT, this is...

quick answer is "No" they will have no way of telling, your pole meter cannot (the ones I know about anyway) turn backwards, so all it will do is not run at all during the day if you make more than you use. Best Ian

Please set your low cutoff voltage higher to 12V , its better to start higher at a higher setting (setting 19 on the menu, it is defaulted to 10.2 which is too low)

A hair dryer has a diode in it for the "LOW" setting, so what its saying (Fault 05) is that there is an unbalanced load on it if you imagine a sine wave power graph, power would normally be used on both the upper and lower portion of the sine wave, but this hair dryer breaks those rules by...

Its really hard to find out what settings you have made to the unit to restrict it from solar charging. The first question what settings have you made , and what do you want the unit to do? From the data, I can see that the unit is stuck in bypass mode, and this is usually a restriction placed...

I try to respond to all my emails on a daily basis, can be up to 50 to 60 + per day between all the other daily emails, yeah I may mis one or two occasionally, just try again. Also please don't send mammoth 9MB Picture attachments, they may bounce from my email server, and I may never see...

Can you explain why you are unable to hook up your generator ? what is your configuration of the LV6548s ?

We get these problems often with any inverter model, but they all have one thing in common. Lithium batteries. If one of your lithium cells is fully charged, and the others are not (even in a fully assembled battery), it will stop absorbing power while charging , this shuts off the charging...

Russ, you have to buy the inverter thats made for the specific battery voltage, there are no switches for this. Buy from the US, so your support and warranty is in the US All the best Ian

one solar assistant for many (haven't tried it on multiple SC48120 but know the developer well enough to fix this if it doesn't) , this is the way it works for multiple inverters in one system (which I have tried, as I use it for my home with 5 inverters) - one USB port per device, you can use...

Thanks Will, we do have stocks for now, but its the crazy season upon us. Best Ian

Will open one up 8048max remove the mainboard and video it for both the 8048max and 5 units we have waiting for spares of the 5000ES (non "US") and wait to see if the others claiming US are any different. Till Monday evening.., should be interesting.

If it was me, with a VMP of 39.6 V each x 2 is 79.2V And thats at room temperature, if it were me, I would connect them in parallel (Max working input voltage on this unit is 80V, so no. I would not)

Hello. First of all your Solar Voltage needs to be above 60V (cannot charge a 48V battery with 48V, you need more), so connect those panels in series again to make them 96V (obviously now you'll have 1/2 the number of parallel strings). The minimum AH battery rating for that system is 200AH...
