I'm not sure actually. I'll have about 14.4 KWh of batteries if I get three batts. Six hours of one AC unit running will be around 9.4 KWh. I'm just not sure if I can get more panels on my roof. I'll be up there taking measurements tomorrow.
Hey everyone. I've been doing some research for the last few weeks planning out my first solar build. This will be going on my 42 foot fifth wheel which me and my family are living in full-time.
I work remote and we are doing a long (3 month) trip across the country this summer. My goals are to...
This is the ideal solution. If I could get the chargeverter in 24V, I'd buy it in an instant. I've found a few battery chargers that can max out at 35 charging amps at 24 volts, but that just won't be enough to offset the AC.
I wasn't taking into account the conversion loss and was assuming...
I don't believe there is any energy management system and even if there were, switching one AC to the other leg shouldn't impact that system right?
Yes two 24v 200Ah batteries and 3150W of panels.
I will most likely be using the propane mode for the water heater. And I'll tell my wife no...
One of those links you sent says that all the panels in a string will operate at the current of the lowest current panel. So if I put the 400W panel which maxes 10A and the 325W panel which maxes 5.6A in series, then the 400W panel will only operate at 5.6A or 226W max.
The voltages don't have...
No I cannot. The Growatts don't have any remote write capability. Read only.
If they did, I could wire up a cool automation with Home Assistant to reduce the charge current when the AC switches on.
I think the only reason I would have to run them in split phase is because shore power coming from a NEMA 14-50 outlet will be in split phase and I'll get the phase error on the inverters if they are configured for single phase. If I'm using the dogbone connector for a 30A outlet, then they will...
I am finalizing the purchase for my 24V Solar Build. I have a Progressive Dynamics PD4560 power control center.
My understanding is that I need to bypass the built in converter and use a 24V-12V converter to connect my batteries to the control center.
However, is there some way where the...
2x Growatt SPF 3000TL, 24V
I have soft starts that I'm going to be installing probably this weekend.
The specs for the power center say it's rated for 120A at 12V. So I think that's why they use a 20A breaker. No matter though, your idea to use that breaker for the AC makes sense.
I...
I'm using the same language as the inverter manufacture per the image I attached above. I've clarified the way my system is configured so hopefully there's no more confusion.
That's basically how I did it. The 24-12V converter is connected to the bus bar with no switch (I'm fixing that this weekend) and the inverter AC output was switched on.
I'll take a look at other panel options. I kinda just picked whatever the cheapest I could get on Santan solar at the moment.
At most, I can get about 4kW of PV in the Growatts (~2kW each). And yes, I'm planning to charge from the truck while driving but there will be many days where I'm...
In full sun, I've got plenty of PV. The issue is the warm evenings and nights.
The battery charger approach won't work now that I did some math. Best I can get is 16A at 24V which is not enough at all to offset the power consumption of the AC.
My best bet at this point is a generator I...
I am installing solar, inverters, and batteries in my rig right now. I've noticed that my power center has both AC units on one of the 50A legs. My inverters are only 3kW each so I'm limited to 25A per leg. I think running both ACs on one inverter runs a good risk of over-drawing current.
The...
I have 2x 3kW Growatt inverters and 2x 24v 200Ah LiFePO4 batteries on my RV. Where I will be staying for the next month, there is virtually zero direct sunlight available to my PV array. I am attempting to charge my batteries with a few hours of generator every day.
I am experiencing some...
I spent the day wiring up my two Growatt 3000TL inverters and EG4-LL batteries in my Fifth Wheel. I am using a 24 volt system and am using a Victron Orion 24v to 12v 70A converter to power my 12v loads.
If I turn the battery on with the converter connected, I can hear the converter clicking for...
I have two of the batteries but I only have one connected right now. Is there a different startup cycle I should be using? It's possible I had the inverter switched on when I switched on the battery but I can't remember for sure.
I am trying to connect my EG4-LL (24V) batteries to Solar Assistant. I have two questions that I cannot figure out.
1. How do I wire up an ethernet cable to the RS485-to-USB adapter?
2. Given the EG4's wonky DIP switch issues, how can I be sure I'm on the right address (address 2 per Solar...
Okay I just took measurements of the roof. It looks like best case, I can get 3.5kW of panels using a hodgepodge of 400W, 325W and 100W panels. It looks like most panels are about 40 inches wide so I can't fit them between my ACs and the edge of the roof without them hanging off. So I'm...
Some other stuff I found out today which might be interesting:
I tested continuity across all 8 pins of the RS485 port on the battery, using the image above as a reference, the following pins are bridged:
1 - 8
2 - 7
3 - 6
I also checked voltage across every pin to every other pin and found...
Thanks for these resources. Believe it or not, I took a few circuits classes in college and should have known this stuff.
There will be two MPPTs (one on each Growatt) which have a max PV input voltage of 150V.
The panels I'm considering have these stats:
Qty
Power (W)
V_oc (V)
V_mp (V)...
