The intertwining of Chinese OEM's and re-branded manufacturers is complex, but in this instance I believe DEYE and Megarevo are head-to-head competitors. Megarevo has no doubt copied DEYE features/format, as Shenzhen/Chinese companies are very good at this. But DEYE is normally very respectful...

Attached is pic of Growatt AXE battery wire. It's a heavy-duty three-wire connector (+ve, -ve, gnd), one wire connector is required per battery stack to connect to SPF- or SPH-series inverters. The 5kWh AXE LFP battery can stack up to 10x (one on top of the other) offering up to 50kWh storage...

I note that Deye (Chinese supplier to EG4, including EG4's new ACDC HVAC unit) also makes a PV-powered ACDC water tank heater (link https://www.deyeinverter.com/product/solar-air-conditioner/hybrid-acdc-solar-air-water-heater.html) It would be nice if EG4 imported that product too.

Depending on inverter model (some have a ground screw on the cabinet, some do not), the battery ground wire should be grounded either on the inverter ground screw or connected directly to the electrical panel ground wire.

If you standardize your tiny home system on 120Vac, stick with Growatt all-in-one but change your model from SPF6000T-DVM to SPF3000TL-LVM . . it charges battery using 120V shore power

Growatt offgrid systems (all connected components) are monitored via their Shine cloud server (connection using optional WiFi dongle). Each AXE battery info is logged . level, charge, discharge, etc . . . using a wired CAN comms cable from AXE(s) to the inverter, then to the cloud/your...

Growatt ARO batteries incorporate very high quality LFP cells (ATL I believe), so higher cost/higher quality ARO pack plus low cost XH inverter makes a very effective hybrid package overall. Would love to see YouTuber review of this.

Growatt-Pylontech inverter-battery pairing initially only worked when SPF setting #5 was set to AGM, which is suboptimal for long-term operation. Vendor Microgreen Solar (Canada) explained that in order to get inverter to communicate with battery: (1) under SPF setting #5, set to LI, which jumps...

What's the SOC (voltage level) of your batteries? SPF AC charger will only begin charging when the battery voltage falls below your setting 12 (48V). Once started, battery will charge from genset until the moment voltage level in setting 13 (52V) is achieved. If you start your generator when the...

For offgrid process and components, you might give folks at Microgreen (Markham ON) a call. They recently did a 30kW offgrid system (using 6 Growatt SPF5000-US) and helped educate the ESA inspector. If you a going grid-tie hybrid >10kW system, the process in Ontario means dealing with the local...

After choosing a Growatt SPF12000T-MPV inverter (a very nice unit) and having my electrician grid-tie it (3-wire connection to AC IN) to charge a 48V AGM battery bank, the local Ontario inspector (an off-grid solar newbie) in Ontario disallowed the system, stating there is no documentation/user...

Many are following this thread w interest . . posting pics of optimal mounting solutions would clear up possible confusion.

Based on my understanding, ARO batteries are designed to be stacked in parallel, but they are high voltage, ie 400V, not typical 48V standard LFP (like Growatt AXE LFP batteries). MIN-XH series hybrid inverters are only compatible with ARO batteries as far as I know. So adding an EG4 48V pack to...

I assume customer is looking for 30kW AC system load capacity which, based on Growatt SPF5000-US specs, could handle up to 36kW DC of panels.

Yes Microgreen ships to USA, typically ground shipment straightforward, contact them via website.

Here's a smartphone screenshot of Growatt's SHINE cloud monitoring's Battery Page for SPF inverter, showing AXE state of charge, charging/discharging, SOC history etc)

Do you have any source for these stainless+aluminum studs? I have a bunch of blank CATL cells that need studs laser welded onto them.

Per other suggestions, Growatt's MIN 5000TL-XH inverter is reliable, low-cost hybrid grid-tie version of your grid-tie inverter. Swap out this inverter and connect to the compatible ARO 9.9kWh battery and Growatt's 50A ATS which will feed a critical load sub-panel during power outage.

I've seen YouTube DIY'ers putting semi-flex PV (Sunpower etc) onto a Coroplast seperator layer then onto RV/trailer roof, both sides adhesively bonded. What is real-world experience with this penetration-free solution for vehicle rooftop PV?

Features questions: RSD? AFCI? 200A pass-through?

Automotive OEMs and parts suppliers (Bosch) etc are making the shift from 12V to 48V for a host of cost and efficiency reasons. RV chassis OEM's should eventually shift to 48V DC systems, but change comes slowly to this vehicle sub-sector. The RV community is hostage to "old" 12V...

Last time I checked, Microgreen Solar (Canada) had a bunch of SYN 200-XH-US in stock.

While not disputing the fact that many European-market Growatt SPF-5000 ES found their way into the North American off-grid market via Chinese drop-shippers, hence creating safety issues due to internally-bonded circuitry, you should note that Growatt designed and launched a full range of...
