Dump Load; SOC; LFP; 7/2022 gear

I've been lurking on the blog and looking at videos and PDFs. Figure it's time to send up a flag.

Where do i find any or all info specific to dumping safely and correctly using SOC and Li for multiple Quattros, Cerbo GX, MPPT RS 450/100, etc? Preferably detailed info.

As for me:
Im a 14 yr off-gridder using a Pb BESS looking at switching to LFP and Victron gear. Even an AC/DC couple system with Fronious if it made sense in the end. Again... no grid for miles.

Ie p 15 thru 18 of:

Looking for succinct material... (or at least what to read and watch) in regards to using the latest victron gear, LFP, and best (safest way) to dump into large water tanks to pre-heat infloor mix. I never used a dump before as unfortunately I've always been underpowered. Thats all going to change.

Again, where do i find any or all of that info specific to dumping safely and correctly using SOC and Li for multiple Quattros, Cerbo GX, MPPT RS 450/100, etc?

I'm using USA 240v Split phase.

Basically, in my humble opinion, a small commercial install in regards to power usage due to amount of PV for pre-heat.

I don't want to destroy the delicate LFP with hysteresis... and or goof up something that i could have avoided by simply learning first from others as "the book" and real world don't always jive.

I want to be an educated consumer, not an installer's nightmare pita.... or the guy relying on the salesman "expert" on every turn.

Respectfully.... and Thanks in advance,

Your Experience with Warranty Claims

What exactly is the warranty when you buy Victron products? Is there a link to "the fine print"?

Has anyone had to claim a warranty for a component that stopped working? If so, how was the process. Did you have to ship the component somewhere? Who paid for that?

bluesolar panel voltage during night > 0 ???

I am not sure if this is normal, so my question is to all of you that use mppt bluesolar charger. While the battery is connected to the charger, I can also measure similar voltage on the solar input terminals. This is regardless if solar panels are connected or not. So if voltage of the battery is 50V, on the PV terminals I can measure 50+ something volts also. Same is displayed in victron connect screen. Does your charger displays solar voltage > 0 during the night also? Shouldn't it be 0V during the night? Perhaps something got fried in mine :-/

Multiplus 2 Repair in Zimbabwe

I have a multiplus 2 5000/48/70 that is overheating but am struggling to find a place to get it fixed in Zimbabwe. One Stop Solar which is listed on the Victron website said they can’t fix it because they don’t sell this specific product or fix products they did not sell. Are there any other service centers in Zimbabwe or do I need to try send it to South Africa?

Generator service notifications

Hi all,

Is it possible to send automatic alarm from VRM if generator service hours are due (hours or time period for example)? It would be handy in case there are many sites to monitor.

Best regards,

Repair training for Quattro

Recently our Quattro Inverter went into an overload situation on it's own. I have contacted my vendor but Victron has asked us to send the unit to San Diego for repair. I would have been very happy if Victron would have swapped it out but I guess that isn't an option. We fulltime RV so being without an inverter is a bad proposition while traveling. My question is how do you become a Victron Certified Technician? Are there membership/certification fees? If I can learn to repair the unit on site then I can order parts instead of sending out for repair. I am a full stack software developer with a pretty good understanding of many of the Victron products that we use in our fairly large system.

What is the "Victron Energy invoice date" ?

The warranty document uses this term - "Victron Energy invoice date" - but i'm not sure what that means.

Can someone define this term? Is it my date of purchase? or the dealer's date of purchase? And if it's the dealer's date of purchase, how do i know what that date is?



Victron Energy warrants its products to be free from defects in workmanship and materials for a period of: Batteries: 2 year limited warranty Li-ion batteries: 3 year limited warranty All other products: 5 -year limited warranty. (See end of document for products that fall under this 5-year limited warranty policy.) As determined from the date of purchase by the end user, with a maximum of 66 months from the Victron Energy invoice date.

Smartsolar MPPT 250/100 in VictronConnect shows load as ESS and 7 seconds later fault appears and back to ESS. Continuously.

Hi all

My system was working perfectly fine for the last 3months. Last week I noticed that the smartsolar power goes to about 5000w and then suddenly drops to 0 every 7 seconds. I have a Quattro 10000va and CCGX. If I disconnect the Quattro and let the smartsolar 250/100 charge the batteries it works fine. Agm batteries 360ah 48v.
