    Battery Balancer by Victron

    I have 2 BattleBorn LifePo batteries in series for a 24v off grid system. Once per month I balance the batteries individually. That means charging each battery up to 14.2 volts using the Victron IP65 charger. (Pretty sure that's the voltage). Well, I'm getting tired of doing it...

    Wires get hot?

    Today my panels produced a consistent 1600 watts. The array is 2S-4P (250 watt panels 40 volts for a 24 volt battery system) The amperage from the Combiner box to the MPPT (Victron 150/60) was around 30 amps and the Cerbo/VRM showed a peak of 33 amps. I checked the wires from the combiner to...

    Cerbo/Venus/Rsp Pi dropping connection solution

    I've been using a Rsp Pi with Venus to watch solar output on VRM. In the past, unpredictably, either the MPPT or BMV signals would be lost and I'd have to reboot the Cerbo/Rsp. The problem has been often attributed to cheap Amazon, non-Victron, USB direct cables. I wrapped a piece of aluminum...

    Easy way to increase PV daily yield

    This is supposed to be funny. I've found a simple way to double the PV daily yield of my array which is 2 kW. Usually, the array only produces 2 kWh per day. Today, a bright sunny one, produced 4.1 kWh after the minor improvements which I describe below. The following method is thoroughly...

    Multiplus- make it not charge batteries?

    I've got a Multiplus 24 2000 and it works very well. The problem I'm having is I lose all of the solar generated energy at the end of the day (let's say 2 kW) after switching from "Inverter" to "On". "On" will fully charge the battery and supply AC loads simultaneously. That's fine but I'm...

    Stop multiplus from charging during the night

    Even when my M+ has fully charged the batteries at night and they're "Float" the M+ consumes electricity. Over night it's almost 700w. That's way too much. Is there a setting to stop the Multi from charging the batteries after the batteries are in Float?

    Turn Multiplus off before Ve-Configure?

    I'm using a Victron Multiplus 24 2000 Compact. After changing the Multiplus settings using Ve-Configure, will 120vac output be interrupted (causing a computer to shut off) when the new Multiplus settings are "sent" to it?

    Disconnect batteries and Multiplus goes nuts...sort of

    Here's an odd situation that happened today. I shut down my system (24v- 2kW) so I could remove an unnecessary temperature wire on my two Battleborn "in-series" batteries. Note- I shut down each component using battery switches beginning at the input to the SCC, then shut down the Mulitplus...

    How about "Rants" forum?

    Rant forums would have massive traffic. First topic would be about stupid time wasting solar youtube videos by theatrical clods with cameras on a stick showing the most important thing to them- their face, and how they can only express themselves using their hands. "Don't forget to...

    Multiplus- Active Ac Input- disconnected?

    Well, here I go again- problems. I just hooked up the "shore power" (we live in a house) to the M+. The inverter output works fine- no problems. However, I looked at the Cerbo (Rsp Pi) and noticed this; See, it says Active AC Input- Disconnected. What does that mean and how do I solve...

    Multiplus Charger settings?

    I've installed my Multiplus Compact 24v-2000 The batteries connected to the Multiplus are two Battleborn in series for a 24v system. What I need to know are; - In the Multiplus Charger tab- what are the settings? I'm getting conflicting information what they should be. Thanks

    Cerbo/Raspberry often drops BMV-712

    I use a Raspberry pi/Venus for a Cerbo GX. Works really well EXCEPT, several times a day the BMV-712 gets "disconnected" and I have to reboot the Cerbo/Rsp. The USB to VE-Direct cables are DIY. Also, the odd (bad) thing is before installing the Cerbo/Rsp the Victron MPPT Bluetooth connection...

    AC disconnect for PV?

    Can I use this switch as a simple "disconnect" between the PV panels and the SCC. Yes, the fuses are missing but I was going to put some sort of conductive metal where they'd be. When turning this switch off, the contacts move really fast. The panels are already fused at the combiner box at...

    Anl fuses vs ????

    My system's a 2kw (soon to be 2.5kW) charging two Battleborn batteries in series- (100ah) I've been using Windynation ANL fuse holders and ANL fuses. So far, no over heating and no problems. It seems that the windynation holders are just lightweight plastic. Any recommendation for a good fuse...

    DIY bus bar fuse holder and battery switch?

    This looked pretty good but then Nate says, "no longer recommended"....but should use Victron Lynx Distributor. $225 Take a look at this- Build DIY Bus bar It sure would be nice to have a clean and neat bus/fuse system. What do you think? Thanks

    Grounding- no idea what they're talking about!

    My system is 2kW feeding two series Battleborn's for a 24v-100ah storage. I'll be installing a Multiplus Compact 24-2000 (2000-50a) inverter/charger Now that part I've become more and more confused about is the grounding of the entire system- both AC portion and DC portion. I assume this...

    MPPT and bus bars in steel cabinet?

    I'm inclined to put all of the solar controls into a steel cabinet and run the #2 wires to my multiplus 24 2000 which will be mounted next to the steel cabinet (with a door on it) Put some fans in there to cool the equipment. Why? I want to contain a fire in the event something bad happens...

    Multiplus- install how close to batteries?

    Is it safe (relative term) to install a Multiplus on the wall above my BB batteries? I know there's no gassing problem but 'am concerned that it might not be proper, electrically, to install the MP so close (within about 6". ....in the event the MP falls off the wall (some how) and hits the...

    Raspberry Pi not showing MPPT

    'Just connected my Rasp 3B+ to my system using Venus os. That part works fine. The BMV and MPPT are both connected with VE direct cables The BMV-712 is found on Venus The MPPT 150/60 is NOT found on Venus I tried changing the cables but no difference. Any ideas how to solve this? Thanks

    Wiring up a Multiplus 24/2000

    My Multiplus 24/2000 arrived today and I'm preparing to wire it up. Our off-grid PV system is a 2kW into two BB batteries in series for a 24v. No grid back feeding will be done but I'll take advantage of the incoming AC to provide an uninterruptible AC supply hopefully with solar priority...

    Multiplus 24/2000- grid back feed?

    I purchased a Victron Multiplus 24/2000 inverter. It hasn't arrived yet. I'm concerned that it'll backfeed the grid though it seems there are some settings that'll prevent that. In other words- with the grid AC feeding into the Multiplus (and also my BB batteries connected to it) I want to...

    Automatic transfer switch?

    Here goes again. I'm now in the market, again, for an automatic transfer switch so it can switch between grid and PV (inverter output) instantly so the computers or refrigerator wont shut off. I read about MOES but want to stay away from it- have read too many complaints. Another possibility...

    Automatic Transfer Switch- which one?

    I've read alot about ATS (plural) and need to install one on my system. My system's off-grid but would like to have an ATS instead of having to plug and unplug extension cords in what seems all the time to reconnect everything to the grid when it's dark and the batteries are low. My system is...

    Best discharge level?

    My system is a 1.5 kW array feeding into 2 series BB LifePo batteries as a 24v system. The batteries, because of the way I use them rarely get below 98% state of charge (hope that's the correct term). Question; am I harming the batteries by not reducing their state of charge to a very low...

    Conductors in Conduit?

    Presently the positive and negative wires exiting from my combiner box are simply laying on the ground. I want to put them into conduit and bury them (pvc)...so the lawnmower doesn't chop 'em up. What is the best means of putting them in conduit- 2 wires (positive and negative) in 1...

    Voltage at panels in darkness?

    In darkness I disconnected the positive and negative wires coming from the Combiner box and to my surprise there was 26.6 volts at the wires. Obviously they are getting that voltage from the batteries (24v system). Is that the way it's supposed to be? Are the panels being backfed at night...

    Full Sun but not full power?

    Well, here's another curiosity. I now have a 1.5 kW array (2s3p) and the system runs quite well in full Sun up to about 400w output from the panels and charging the batteries and then feeding the Inverter. The MPPT shows "Float" so all is well. However, with no load, when I put a heavy load...

    DIY Transfer switch

    It like to make or maybe purchase a transfer switch so I can, obviously, manually quickly switch between solar (inverter) and grid and not have to shut down the appliance or device that's being used. I figure if I flip the switch fast enough there wont be any loss of power to the device. For...

    Full Sun but Power from Batteries?

    I'm new to this and my 1 kW (24v) system is running very well. Here's a curiosity- though there's full Sun and the batteries are charged to Float, when I put a load on the system of 90w, through the inverter, I'm running totally on batteries UNTIL the battery voltage drops to about 27v and...

    Victron MPPT 150/60 settings for 24v system?

    My 1kw 24v PV system became operational today. So far there have been no problems and I'm amazed how well the Victron controller works. The mppt is charging two Battle Born 12v-100ah batteries in series making it a 24v 100ah system. I don't know that exact settings that should be used on the...
