AEVA Forums

I've only recently joined, Welcome to the forum, and thanks for the kind words. However, upon reviewing the factory firmware within the inverters I note that it reports as 74.50. I have not seen mention of any firmware revision beyond 74.40 on this forum. Thus my question: can I safely downgrade fr...

On an MPPT PIP you can go up to the max PV voltage of 145V without problem, if you go 1V above it switches off. I would not say "without problem". From 130V and above, it's been reducing its maximum power to protect itself, and by 145V, its absolute maximum voltage, the power has fallen to zero. Ab...

Hy, i have a new Steca Solarix PLI 5000-48 bought in January with this Firmware: 72 40 Is it usefull to flash the patched one`s from here. ( 72.20e? / 72.40e?) 😔 Your inverter appears to be a 64V model, so the applicable fully patched firmware is 72.20e, not 7 4 .40e. The behavior of the charging a...

I was celebrating too early. Under full sunlight the PWM charger switched off again and showed 92V on PV input while battery was on 54V. ... Trying with 3S solar string tomorrow. I would not attempt 3S with the PWM solar charge controller! You'll have some 138V, which is well over the rated maximum...

Here in denmark it is normal to mount panel parallel to the roof, many installations like this, often mounted directly in roof or holes with absolutely No possibilty of air flow. Wow. I learned something today! :) Also, your summers must be rather mild compared to ours in most of Australia, where w...

Affer , those panels look to be mounted flat to the roof. That doesn't allow for air flow under them, and they can overheat. Weber had a customer who called him in to investigate an under-performing system. The panels were bolted directly to a corrugated roof, and they overheated. I ended up buying...

This weekend I mounted 4 flexible Solar panels 70W each to a wall of the house to capture low standing evening sun (and to see if these super cheap panels do actually work) I connected them to PV input of phase1 PIP. Unit shows 90V on input, but no charging of my battery starts .... I have checked ...

Ethics aside, I doubt that it could be done. They really are complex beasts.

Yes, the members' machines don't have to be completed. In fact, the build stage is usually by far the most interesting stage.

Could it be used to operate a relay (SSR or similar) when the battery is full - switching the PV to the MPPT heater controllers? Not really, unless you never want automatic utility charging. It's designed to start a generator, so it comes on when the battery is weak, and off when no longer weak, or...

Hi Coulomb Sorry I tried all my usernames. I meant search for some word (not just potential user names) that you would likely have used. For example, the model name of a car you owned or were interested in, that sort of thing. Some sites offer lost username???? I don't know how that would work. Our...

I tried to get my old password re-sent. That was great but I have no idea my username. Can someone direct me to how I can retrieve my username?? Can you think of a relatively rare keyword that would have been in one of your earlier posts? We have posts going back twenty years or so, so you could se...

In the US, the larger of the two battery sizes goes from 72.6 kWh (international) to 77 .4kWh (USA only I believe, though he says North America). But they get less froot (frunk for them) space.



[ Edit: 77.4 kWh is USA only, not Canada, it seems ]

$68 extra! (Lowest cost model)

Why he acquired the form "55355535553555" I do not understand. In XtractorFan's case, he received a new control board from his supplier. New boards seem to come with this serial number. They should be customised for the inverter-charger's actual serial number, but apparently this step was not perfo...

I have a particular application in mind where I would want 3 MKs in parallel operation to provide the required output capacity, but the available supply would be lower, except unlike the situation for atomi, my supply could reach 5kw. So my question here is what would happen if I had 3x PIP-5048MK ...

The brochure shows 5 single person liftable boxes that represent the upgradeable modules. Presumably the lower two represent the cable options and the upper three are the 25kw power increments. Ah! I wondered about those two lower boxes. Maybe they are what chops the ≈1000 VDC bus voltage to whatev...

I got the impression that the PKM chargers were an entirely different product intended for fleet depots and the like rather than street parking. Ah, that could well be true. I mentioned them because they were all I could find on the Tritium site. I guess they don't want to offer details on far futu...

I measured the charge port (just a positive and negative and noted about 2v with my multi-meter) ... I've tried to charge it for a few hours and measure the charge port voltage which is now about 9v. Ouch. You need to be very careful recharging cells from very low states of charge; that's when they...

The Tritium RTM charger is capable of being installed with just 25kw and grow to 350kw shared between two cables. It's my impression that there isn't a single model that can start out as a 25 kW unit and grow all the way up to a 350 kW unit. The RTM75 can come as 25, 50, or 75 kW, and be upgraded i...

Hi All, I would like to have my MPP5048GKs basically in battery mode. (01 SBU) I want them in line mode from 22:00 until 9:00 next day Interesting that these timers can only be set when the removable display is connected to a GK/VM III, not an MK/King. The manual is not clear for me: Is it correct ...

I've definitely read posts of people doing this, but I'm not sure what EVSE they are using. Many EVSEs have this capability. I use one on my Gen 1 Leaf (Zwet brand) that allows me at the push of a button to change the current limit from 6 to 16 A in steps of 1 amp. Most wall chargers have DIP switc...

Hello all, new to the forum, I can be quite good in the numbers. Welcome to the forum. Questions. (assume I can get a sparky to have a normal socket out of the controlled load meter) with its own 20amp circuit. You will probably want to get a dedicated 32 A circuit, so that you can let the car draw...

The lesson learned here is that firmware version 54.10 machines can be upgraded to patched firmware 74.40e in my experience. Interesting, thanks for the post. I worry however whether the 4 kW model can handle 5 kW through the transformer. But you have a 4 kW and a 5 kW more or less side by side; ca...

These are my settings I use: 12 48v 16 SLB UCB in winter time, otherwise SLB UdC 29 47v It is my understanding that at a battery voltage of 49 V (setting 29 plus 2 V) or below, you should switch to "utility source". For the MK/King, I believe that this is "line mode" (double conversion), unless you...
