    Bleeding the inverter capacitors

    When I was troubleshooting my Lifepower4 firmware upgrade in this thread, I noticed that I had residual voltage on the battery rack busbars after shutting off each of the individual battery breakers. I have since determined that this voltage is coming from the Growatt inverter capacitors...

    Power Company - bad neutral - no meter for over a month

    Curious if anyone had run into a similar situation... A couple months ago, I reported to the power company that we were experiencing pulsing lights whenever the washing machine would go into agitate mode. Lights would also flicker at random times throughout the day. I measured fluctuating...

    48VDC Rack Mount Batteries - Grounding

    I have searched, but there appears to be conflicting information about battery grounding in a fixed home installation. Of all the rack mount videos I have watched, nobody ever talks about or shows grounding of the rack. How is this done, and what gauge wire is typically used? I see some...

    Highest kWh usage vs main panel breaker

    I came across this interesting video about selecting circuit breaker size for powering an EV. It was different than what I was expecting and the guy went into figuring out how much panel current you have available before sizing your EV breaker and outlet/circuit. This prompted me to go onto...

    LF Inverters and unbalanced loads

    Recently installed my Growatt 12k LF split phase inverter and 20kWh 48V battery rack. Did another test yesterday and everything worked great, though I did have an unbalanced load when the landscape lights came on. I'll have to rearrange some circuits in the load center to better balance loads at...

    Growatt 12k latest firmware

    Does anyone know what the latest firmware version is when viewing it on the screen? Mine indicates 074-02-507. I can set the beep to off in the configuration screen but it doesn't stop the beep when you press a button. The unit always has the speaker icon on. I've been researching firmware...

    Anyone mount solar panels to a fence?

    I'm curious if anyone has thought about using a fence to hold some panels, mounted vertically. It seems the only place I have decent solar at all times of the year is on this fence. Was thinking about attaching some horizontal rails to the posts, then attaching panels to the rails. Each...

    Growatt 12k setting 13 (Utility to Battery Transfer Voltage)

    I was testing our emergency backup setup today and when the battery reached 90% the inverter temporarily shut down and restarted. I had setting 1 set to UTL and setting 13 (Utility to Battery Transfer Voltage) set to 90%. Based on how I'm using this inverter, I think I need to change setting...

    Signature Solar 6-space rack

    I just received my order from Signature Solar this week and everything seems to have arrived in good condition. I haven't mounted my inverter yet, but the pre-assembled rack and batteries are all set up, fully charged and functioning correctly. The one thing I noticed is that the Lifepower4...

    Growatt 12k LF Question

    For those of you who own this unit: Looking at the manual, there are 3 different modes you can choose: 1. Standby Mode - PV power only charges batteries 2. Line Mode - Utility/generator powers loads, batteries charge via PV first, then utility/gen. 3. Battery Mode - Output from batteries and...

    Battery to Inverter Class T Fuse value

    Looking for confirmation before I purchase. This is the fuse Will Prowse often links on his videos for battery to inverter setups: https://www.amazon.com/gp/product/B001539B60/ I will be setting up a system with four EG4 48V 5kWh batteries in an EG4 server cabinet with busbars, connecting it...

    LVX6048WP unconventional AC connections and questions

    So, if anyone has any experience with the MPP LVX6048WP model inverter and general AC connections, I have a strange configuration I need to brainstorm to ensure what I'm doing is going to work as expected. I'm in the process of building a "detachable" emergency battery backup system to power the...

    About to place an order for battery backup system...any red flags?

    OK, after much research over the past few months, I'm about to place an order for a new battery backup system which I can take with me when I move. The purpose of the system is to serve as a secondary 240V split phase backup generator for my house. I will use my Honda EU7000is during the day...

    Split-phase inverter for battery backup use only

    If you were to purchase a split-phase inverter (or two parallel capable inverters) today to go with three 48V 5kWh rack mount batteries for emergency backup power...what model would it be? Looking for something to compliment my Honda EU7000is backup generator so I can run on battery at night and...

    Rack Mount LIFEPO4 wiring between batteries

    When I see examples of people's battery racks with wiring between batteries, I wonder why they do it this way: https://www.mobile-solarpower.com/uploads/1/2/9/6/12964626/20220320-165103_orig.jpg Would the current be highest heading into the wire of the last battery, and lowest flowing from the...

    Backup to a generator for prolonged grid down scenario

    I've been researching and reading about solar/battery solutions for a few months and haven't quite figured out the best approach to meeting my requirements. I'm hoping someone here has gone through the same process and can offer some advice for my current situation. I'm trying to prepare for a...

    Parallel different types of inverter generators

    Anyone ever try paralleling a battery inverter generator with a regular inverter generator? For example, would an Ecoflow Delta Pro or Bluetti AC300 play nice with a Honda EU2200i, EU3000is or EU7000is since the Honda can detect a waveform and match it? I know most people who try to parallel...

    Easiest solution to provide generator "boost" for HVAC peak inrush

    I have a Honda 240V inverter generator (EU7000IS) that I use to power my load center via interlock, 30A breaker and input box during power outages. The generator powers the whole house with the exception of my main HVAC unit. What would be the easiest and least expensive way to add a battery...
