Hello my name is Kevin, and I’m addicted to solar & LiFePO4 battery tech!
@Chunk48 retired now so I've got way too much time to obsess over this stuff 😄 Started with a single 100Ah Fogstar Drift and thought "that'll do nicely." Three years later I've got...

Adding a YIXIANG V3 Stacked Battery Box Kit With JK 200A BMS to my setup....maybe
RetiredEngineer86 | 2,847 posts | ⚡ Tinkerer Emeritus The YIXIANG V3 stacking system is decent for the price but double-check your cell bus bar torque specs — I had a nasty high-resistance...

Clarifying breaker & wire size needed for AC-out on Multiplus UU 48/5000 120V
@IanPearce56 UK 230V system so your AC-out is single phase — the 5000VA rating gives you roughly 21.7A continuous at 230V.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@ThistleKen done exactly this on my setup — had a 12V Alpicool chest freezer running off a 200Ah LiFePO4 last summer. Key thing @GrumpyBuilder is hinting at: ambient temp matters massively.

Anyone else struggling to keep the leisure battery topped up on shorter winter drives?
@BurnGlen classic winter problem this. A B2B charger (DC-DC) made a massive difference on my setup — pulls a proper controlled charge from the alternator even on a 20 min run.

Swapped out the old Victron for a Renogy on the narrowboat — worth it?
@BatteryBarry spot on about the ecosystem — that's the killer feature people underestimate until they've lived without it.

Generator won't start after sitting in the shed all winter — carb issue?
@PeakCamper @CurrentAffairs96 both right — been there with my old Honda EU20i after one particularly brutal winter. One thing nobody's mentioned: fresh spark plug.

Deciding weather or not to keep one 12v battery in a 24v 5th upgrade
@MelKing83 been there — I ran a rogue 12v alongside my 24v bank for about 6 months powering just my 12v fridge directly. Kept it isolated, charged via a Victron Orion DC-DC.

Anyone else find their garden office heats up way too fast in summer?
RetiredEngineer86 | 2,104 posts | 🔋 Battery Nerd External roller blinds made a massive difference on my shed/office combo — stops the heat getting in rather than trying to shift it once it's...

Cxeny 48V(51.2V) 125Ah LiFePO4 Golf Cart Battery Kit | $992, US Stock Free Shipping | 5 Year Warranty
@Bomber78 the warranty piece is what kills it for me really. 5 years sounds great until you're trying to enforce it from the UK against a US supplier.

BMS SOC is Different from CerboGX Display
@LochLover had exactly this with my setup last year. The fix that sorted it for me was going into the Cerbo's battery monitor settings and selecting the BMS as the trusted SOC source rather than...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@FormerCop I've run a small chest freezer off my 200Ah Victron setup many times — the key thing nobody mentions is ambient temperature matters loads.

Battery fuse blown = wrong voltage reported by LynxBMS
@StuKnight yep, been there! Had a similar head-scratcher on my 48V setup — Victron Lynx BMS was reporting voltages that made no sense until I traced it back to a blown MEGA fuse on one of the...

House Consumption shows 0 W after adding Huawei SUN2000 to Victron ESS
@KevLee had almost identical bother when I added a second AC source to my own setup. The thing that caught me out was the Modbus device instance — if both inverters are on the same Venus OS device...

Zusammenspiel Solarspitzengesetz (60%) und Systemeinspeisung begrenzen für nicht Victron AC-Inverter
@EmmaEdwards82 good shout on the G98/G99 distinction — that trips people up constantly. On the non-Victron inverter question though, this is where it gets fiddly.
