Only settings as per my doc attachments. nothing else.

Agreed, Allgrand are brilliant.

Thanks once again for your input and brain scratching. Let me input the above and see how things go. As things stand at the moment, I have HV cut off at 28.8v but battery voltage never reaches this, always 27.6v. Will keep you posted.

Yeah, definitely the black sheep in the inverter family.

That is it.

Ok so the PDF thing isn't going to work as I'm not paying for the app, and due to the 3MB file size restriction here I'll be sending through 4 or 5 posts. I've left out all the connection and maintenance info.

Customize THE specified battery settings yes, default low voltage and high voltage cut offs and float are not correct according to the battery manufacturer. As to why have equalization at all, there are still those on forums and certain battery manufactures who insist vrla gel must be equalized, just maybe the inverter manufacturer is one of them. I will make a plan to upload the manual.

Something wild came to mind while going through the manual for the umpteenth time. As there are no default battery type settings to be found and based on the pic I posted which only indicates VRLA battery type with a charge voltage of 13.8v, what is the possibility that this Inverter is only meant for VRLA batteries and the charge voltage is preset, hence no adjustable settings for other battery types. This would explain why only float, equalization, low and high cut off are adjustable. I also set equalization to 0v due to the gel's I'm running, after reboot it defaults to 14v. What are the chances?

I'll keep you posted to any further outcomes with my investigation. No, you aren't going to find anything relating to this Inverter on the web, I've spent just on 2 weeks searching and nothing.

I can try using equalization as bulk but I'm a bit hesitant to try this as equalization for a gel is a definite no no especially as there is no time setting for a specific charge setting on this inverter, unless it is done automatically. A lot of money down the drain if things go south battery wise, but I guess there is only one way to find out. Cheers for your input.

I have float set at 13.6v as per battery manufacturer specs. This no setting for bulk or charge voltage blows my mind. As per the attachment they talk about a charge voltage for VRLA but as mentioned there is no setting for this. I can try using equalization as bulk but I'm a bit hesitant to try this as equalization for a gel is a definite no no especially as there is no time setting for a specific charge setting on this inverter, unless it is done automatically.

I spoke to my local battery supplier and he suggested I set equalize to float which is 13.6v as per Allgrand data sheet, agreed equalization is a no no for VRLA Gel hence setting the 2 to the same voltage.. This inverter does not have any time settings. Everything seems to be working fine but let's see how it goes. Cheers for your input.

Hi All, I'm also running VRLA Gel batteries. I read somewhere on this forum setting float at 13.6v as recommended by the battery manufacturer Allgrand, equalize can also be 13.6v., thus eliminating any further costs for a battery balancer.

Hi all! So so new to solar community, I purchased this Inverter due to the price and apparently being able to connect up to 8 via a dongle. I have 4 200Ah Allgrand VRLA gel batteries connected in s/p with 2kw of panels. So here is a conundrum for all the inverter specialists out there. This is my third post, hopefully someone will reply. This inverter has no battery selection type setting, no bulk setting in user mode, in fact there is only a user mode. Battery settings as follows. 1. Equalization. Which is a big no no for gel and according to Allgrand spec sheet. 2. Float 13.6 Allgrand spec 3. High voltage cut off. 4. Low voltage cut off. So my question is, if there is no default setting for Gel or AGM, no bulk charging or absorption setting how is one supposed to charge any battery. Either I'm dof or this is a piece of shite. No response from numerous big companies selling this item. Thanking you in advance.

Any advice here please. The above inverter has 4 battery voltage settings. 1, Float voltage 2, Equalization voltage 3, High voltage cut off 4, Low voltage cut off There is no bulk voltage setting, this has got me baffled. Any advice would be much appreciated. I'm running 4 VRLA 200Ah gel batteries, series parallel to give 24v at 400Ah. Thanks in advance.

Good Day Some assistance here please concerning the below points. I have this grid tied inverter with 2 200ah Allgrand VRLA gel batteries in series. 1) Equalize charging voltage - what should this be set at? 2) Battery high voltage cut off - would this be the same as bulk charge, as there is no mention of bulk charging voltage settings in the manual. One of my main concerns. 3) AC supply-Battery supply voltage point. This is only selectable in PV and battery priority mode. Thanking you in advance.
