Not a bad problem to have. I started noticing a week or two back that my array generation is, in addition to covering the house load, fully charging the 5kWh battery by about 2.30pm to 3pm. By about 9pm-10pm the battery will be empty as family come home and leave everything switched on. If the...

Hello, I have a WZRELB 3000W 48v split phase off grid inverter that I've been wanting to put through it's paces so decided as it's nice and sunny to take the house off the grid for the day and see what the inverter could do. I noticed when I ran the dishwasher that the 120V leg that its...

Hello all, Do you find as you're on this solar journey that you've reached a point where stuff works well enough, and anything beyond that becomes wants over needs? Where do you draw the line? You could spend the money, but do you need to? How do you justify it to yourself? I'm in that...

Hello! I have four 12v LiFePO4 batteries in series for 48v stored in an attached and insulated garage. A battery balancer was installed about six weeks ago and has kept them within .1 to .2v of each other. The charge controller the batteries are connected to has a low temp cut off which I...

My CC has a 150v PV limit. My 4S3P array normally runs at 120V. The last couple of days I’ve found the CC blinking E10 indicating the array voltage is too high. I was surprised by this as it’s been warmer than normal (40F vs freezing). On each occasion I shut off the PV in, waited a few...

Hello! I have 4 x 12.8v LiFePO4 batteries in series for 51.2v, and would like to purchase an AC charger for the days when there's nothing coming in from solar, etc. The options I've looked at are... EG4 Chargeverter from Signature Solar, Current Connected, etc. - Tempting as the batteries...

Hello! I recently purchased a WZRELB 48v split phase inverter [1] with the intention of using it for house backup in an emergency. The big sell besides price was that it was split phase and can allegedly be connected to the house panel. There's even a section in the manual about doing that...

Hello! Current setup - 3kw PV array to 48v 60a charge controller to 48V LiFePO4 5kw battery feeding a zero export grid tie only inverter. I'd like to add a 48v off grid inverter for grid down situations, and would really like it to be split phase. The breakers for the cooker, AC and dryer...

Hello! So AOLIthium are advertising their rackmount batteries on Black Friday sale for $999 (USD) shipping from CA. Given that's at least $200 cheaper than anything elsewhere I'm wondering what the catch is. I didn't check the shipping costs so perhaps that's it. Does anyone have any...

Hello, I have 4 Weize 12v 100ah batteries purchased from Amazon between late June and September of 2023. Initially the first two were in parallel running a 12v inverter. I decided to go to 48v so purchased two more. They have been running in series for about two weeks. The last couple of days...

Hello, I've seen numerous inverters e.g. PowMR 5kw, etc that can work in split phase if you wire one for each phase, and in parallel up to 6 inverters for 30kw. I have two questions. 1. Does each inverter's hot go to a single pole, and then the neutral to the neutral bar, ground to ground, or...

Hello! I have an HQST 60A SCC that can charge 12/24/36/48v battery banks, and recently moved from 12v to 48v. (12v100AH in 2P to 12v100AH in 4S). I added a 48v to 12v transformer on the load port so the lights, usb, etc would continue to work. The load output is normally turned off. The SCC...

I'm considering buying a smart shunt. Why? I currently have 4 x 12v LifePO4 batteries in series for 48v. The HQST 60A charge controller gives me estimates of what it thinks remains based on voltage but I'm not sure how accurate it is. It gives voltage and a percentage SOC, though there is no...

Curious on thoughts over this bit of news. "Proposed Utility Tax would increase electricity bills for millions, undermine rooftop solar, and discourage conservation" https://solarrights.org/utility-tax-post/ It makes me so glad I don't live in CA. I mean, you go to these lengths to be self...

Hello, My charge controller* supports 12/24 and 48v batteries. Currently it's connected to a 12v battery. I'd like to utilize the dc loads terminal on the controller and assume I can just add one of those fuse blocks like you get for RVs and then maybe run 12v USB or lights. It seems silly to...

Hello, I have one 12.8v 100AH LifePO4 battery, soon to be two. Same brand/model/weeks between purchases. 1. Parallel process Before anything else I should charge them independently to full, then leave them in parallel to each other but disconnected from everything else for 24 hours, yes? 2...

I have a 12v LifePO4 battery and inverter. Some devices exceed the 100A BMS limit longer than the few seconds of 200A burst it supports. I decided to add a second battery to share the amps. e.g. 1800W coffee maker, 140A draw, 70A per battery. I was just going to parallel the second battery with...

Hello, So I've been going back and forward on this situation for a while. - My array is just over 3000w of 260w panels. - Heavily shaded by neighboring trees, just one small part of my property is good for solar. - Even then a chimney stack obscures part of it until late morning. - I have two...

I have a 12vdc 3000w inverter putting out 120vac. Link and image attached. It's in my garage and I'd like it to power a few things there. From the image the inverter has a terminal block with what I think is hot, ground, neutral which I'd like to install a small 120v single phase panel with a...

Hello! A friend of mine had the following installed on his home last year. - 7.6kW array (19 x 400w Q.PEAK DUO BLK ML G10+) - SolarEdge HD Wave Inverter SE7600H-US (240v) - SolarEdge P401 Power Optimizers for each panel. He's in the miserable heat that is Texas, and interested in batteries to...

Hello, I have… - an HQST 12/24/48v 60a scc. - a Weize 12v 100ah LiFePO4 battery. - a 12v 3000w psw Inverter. - pos and neg bus bars. - 6awg cable for the scc to the bus bars. - 2/0 awg for the battery to bus bar. - 2/0 awg for inverter to bus bar. - 63a din breaker for scc. I think I need to...

Hello, In interested in adding a hybrid / all in one inverter to my home. My concern is that the array / batteries will not be able to high load situations, therefore I'm looking for a system that can make up the shortfall with grid power e.g. early morning with PV still charging battery...

Hello, I own some 48v inverters I'd like to use with an EG4 48v battery. Although the inverters don't have communication ports for RS-485 / CAN bus, the battery cut off / start up voltages can be configured. The plan is PV to HQST 60A SCC (with RS-485) to EG4/LL to said inverters. I...

Hello, I'm looking for a reliable budget charge controller with the following specification. - handle 12/24/48v and up to 60A. - solid terminals that can support sufficient gauge for PV and battery (12v 100ah lifepo4 to learn with, and at some future date, 48v 100ah). - will last more than a...

Hello, I have two 2000W Sun GTILs. They are configured identically, with each linked directly to it's own 1500W PV array @ 60V. No batteries. They are supposed to be able to take up to 30A (which at 60V would be 1800W). I had them set at 25A / 1500W to be safe. The first one, in service since...

Hello! My inverter has a single +/- DC input and can be connected to either PV or a battery. It has built in MPPT, and all it cares about is that the DC voltage meets the startup minimum of 49V. It is currently connected to a 1500W 60V (2S3P) PV, no battery. The PV voltage with no load is 60V...

Location US, on grid, standard L1/L2 split. tl;dr; if the main home breaker is off, can an off grid split phase inverter be used instead of a diesel generator? Any neutral/ground bonding type issues to worry about? Should just be like a generator/240v receptacle feeding it right? My home is...

Hello! I'm not sure if this is the right section to post in but here goes. I have an SPD in the combiner box on the DC side of my string inverter. On the AC side all I have is a regular CH breaker in the home breaker panel. I am considering adding a whole home SPD (e.g. the Eaton CHSPT2SURGE)...

Hello, So, the Sun GTIL inverters, they're great in that they can take PV or a battery, connect to a breaker in your panel, and come with zero export CT clamps. There's no need to have a separate loads panel installed, and they're budget friendly. If you want to offset generation to non sun...

My current setup is a 2k 60vdc array in 2S4P to a 2kw 45v-90v inverter. I'd like to add batteries and have been looking at buying four 12.8V LiFePO4 batteries from Amazon as they seem readily available, and putting them in series for 48v (51.2v), with a suitable charge controller. I'm super...
