I've been having some issues connecting my battery monitor to an orange pi for solar assistant. The battery monitor I have uses a RS485 connection. On the monitor, the connection is a little smaller than a phone jack. (not sure what that's called) I was able to grind down a phone jack to fit...
As others have said, watts are watts. So it's the same. You may be confusing the amperage difference at different voltages. Just use volts x amps = watts. So say you have a 200 watt load on a 220v line, that is .9amps, but that same 200 watt load on a 48v line (like your battery) would be...
Just got a few more panels in and one of them looks odd in a small area. I have not tested them yet, but is this a shorted area or other manufacturing issue that will effect the panel (more than likely at least)?
Looking at that, it looks like most micro inverters except it does not shut down in a power outage but will continue to power the output but not feed the grid (if I'm reading that right). What I'm curious about is when your solar is producing more than you're consuming, not feeding the grid...
All these replies but really no attempts to answer... so does anyone know of a 120v version of one of these "immersion heater diverters"? Or perhaps if they would function on 120v rather than 230v. :)
See the attached pic. I had the microinverters on which were pushing around 550w. They are only on phase A which is the orange graph. (Phase B is blue). I turned them off and you can see eyedro showed a power use reduction (opposite of what it should). I turned them back on again and as they...
Let's say you have one battery and the manufacture recommends charging to be under 20A. Straight forward enough. Now let's say you add a second one in parallel. Since that doubles the capacity, does that mean it doubles the max charging current? So 1 battery, keep charging under 20A. 2...
Hi there. New here. I searched and could not find anything on this. So basically, I just got the hybrid LV2424. It will only have about 680w of PV panels connected to it. The plan was to have it grid tied to supplement the current home grid usage (generally between .6-4kw). I'm confused as...
So what is recommended to hold the batter at for a 24v LifePO4? 27.2 since that's resting voltage for most, or more like 28.5 which I have as charging. Or something else?
No-brand cheap micro inverters. So they directly take the PV and convert it to 120v where it is tied or plugged into a standard 120v outlet. I have a few running like this, but all tie into the same leg of the meter. A single CT should be able to see this surplus production as they are only...
I'm trying to figure this out. I've been using eyedro to monitor electrical usage for years now from the grid. The sensors are on the main lugs coming from the meter as they should be. Now the odd thing is when I connect PVs on micro inverters which are then grid tied, it shows an increase or...
With a LifePO4 battery, is the idea to allow it to pretty much drain it before allowing the solar charger/inverter to charge, or should it be topped off when there is sun/solar energy coming in and no load? I ask because I assumed they should always be topping off, but with my HV LV2424, it...
I'm looking to use a 485 connection on my battery monitor to connect to my solar monitor (orange pi with solar assistant). My battery monitor uses a phone jack (not ethernet) and my solar monitor needs a usb connection. That wiring diagram is simple enough for the 485 side, but I don't know...
Currently have a 24v LifePO4 battery being charged/used by a MPPT charger/inverter combo (MPP solar HV-LV2424 (green)). I currently have it set to charge to 28.5v. I was thinking for adding anther small array on a little PWM charger (says it auto selects 12v/24v) to the same battery. (Main...
My air conditioning compressor pulls about 1.25kw from each phase (2 phase, USA). They are both currently on the grid. I would like to move one of those AC breakers over to an off grid system. Do you foresee any issue with this? I'm not entirely sure if the sine waves need to be offset from...
Great, thanks.
Now say in the future the grid is down for a while and I need to convert this over to off-grid... Rather than rewiring the loads to the AC output, I could essentially disconnect the main (so there is now island protection) and move the break box connection over from AC in to AC...
I was curious how most home power meters work. In the US, with 2 legs or phases... Lets say you are using 200w on each leg/phase, so 400w total of grid power. Now lets say you add solar to only one leg/phase but don't want any export. Now if on that one leg/phase you added it to, lets say...
I currently have a 24v system running 2 LifePO4 24v,100ah batteries in parallel. I wanted to add another battery, but noticed it's quite a bit cheaper to get 2 12v, 100ah batteries (same manufacturer) rather than another single 24v 100ah battery. I realize these would need wired in a series...
