Thank you - great info as I missed those facts in the manual…from the Wombat

Building 4000W solar array to power two EG4 6000XP inverters in parallel with two EG4 PowerPro batteries in parallel. I read the NEC requires a DC ground fault protector to disconnect PV+ line to prevent fires. So I called Signature Solar tech help and they don’t sell the device and do not...

Yes I had a Lynx distributor but I wasn’t able to find the Victron MPPT manual’s recommended 80-100A Megafuse in 58V size as Victron doesn’t make 58V mega fuses that small. I ditched the Lynx and will use an 80-100A 48V ANL fuse as I am unfamiliar with NH fuses.

1/0 gauge ampacity is 170A X 1.25 = 212A fuse - nearest is 200A T class fuse battery line. MPPT line 70A X 1.25 = 87.5A fuse - I have used ANL fuses before - can I continue to do so using one with a close match to 87.5?

I have 1/0 battery cables. What is your recommended T class fuse size? What wire gauge would you recommend from my 48V battery to the MPPT and what size fuse do you recommend for that MPPT wire? Thanks.

Planning totally off grid EV charging and 240V supply to pool heater. Two EG4 6000XP in parallel to two EG4 PowerPro batteries for 50A 240V supply to an off-grid service panel - grounded to earth ground via continuous 6g copper wire attached to two 8 ft pounded into dirt earth-ground. There will...

Converting 12V system to 48V - 15,360Wh 300Ah battery equivalent wired to 1,820W Solar connected to a Victron Multiplus II 120V 48/3000/35-50 and a Victron SmartSolar charge controller MPPT 150/70 Tr. Victron Multiplus II manual recommends 125A Mega fuse on battery line to inverter but many on...

I forgot that the neutral ground bond clears the fault. My error. Thanks for clarifying Timselectric.

One more question regarding NEC 690.47(A)(1) - most PV systems are functionally grounded rather than solidly grounded. Mike Holt says that for functionally grounded systems, the inverter equipment grounding conductor is connected to the grounded distribution equipment. This connection is used...

Thanks good to know 6AWG is overkill. I will eventually have two ground mounted arrays, each delivering Vmp 310V PV array current 13A. What size copper do you recommend?

I have a 4000W ground mounted array >100 feet from the house. Even though NEC 690.47(A)(1) says that “the PV output circuit is the only connection to ground required for the PV system” do you recommend I still run 6AWG copper ground wire with my PV cables in a buried conduit to join with the...

The 5 HP pump runs the swim current for the Endless Pool and is built in and cannot be switched out. To get over the inrush surge that could overwhelm a high frequency inverter, I wonder if placing a Soft Start on the power line could reduce the surge to tolerable levels. I see that Will Prowse...

Thank you all. I bought two copper ground rods and drove both 8 feet down 10 minutes each about 7 feet apart - review of my house plan showed the riprap boulders were further south from the site of the ground rods. I connected the two rods with a 6 AWG copper wire. Problem solved.

Planning off-grid 240V 25A EV charge system with EG4 6000XP inverter and EG4 PowerPro 14.3 kWh battery in my house garage. My house is built on riprap (boulders to raise it above a flood plain) which I cannot drive an 8 foot grounding rod into. Nearby is a steel garage on concrete pad - I...

Thank you…you did a great build

Great use of pipe. Question what did you buy to connect the transverse 2” pipe to the vertical pipe - looks like you mounted something on the top of the steel pipe and connected two U bolts. Home Depot?

I bought a Midea window air conditioner model MAW12AV1QWT 12,000 BTU $420 online Costco but in the store I got it for $280. I built an extension to my “shed” putting the AC 2 feet from the electrical equipment so my butt can fit there for maintenance work. It works great, effortless cooling the...

Thank you all of you for your suggestions. I really don’t need a truly “certified outdoor” inverter and as a retiree, my budget can’t be in the thousands. I need a lowish power output pure inverter that can operate at the elevated temperature experienced in Phoenix - the inverter will be...

There is water from a tap and I have that same evaporatIve cooler. Good thought but I wonder how much water that uses daily?

Outdoors I set up a shed with EG4 6500 EX48 with one EG4 Lifepower 48V battery to run LED lights on my gazebo, internet, chargers and occasionally use it to power shop vacs, etc. Problem is that the maximum operating temperature of the EG4 EX48 is 104degrees F and I live in Phoenix where the...

Thank you..this helps me understand better to expect the 30+% drop in battery and I will get another battery. I don’t see such a large a drop with the Giandel inverter in my garage or with my Progressive Dynamic inverter in my RV or with Victron.

I have a single EG4 6500 EX48 with one EG4 Lifepower 48V battery to run LED lights on my gazebo, internet, chargers and occasionally use it to power shop vacs, etc. I have 6 solar panels in series 240W each and every night I get sufficient solar to bring the battery capacity up to 100%. By...

Thanks to all for advice. Project finished with covers over breakers to prevent accidental shut off. i put a breaker panel between AC in to AC input on the EG4 inverter and a DC breaker between the AIMS battery charger and the batter. it works fine.

Thanks…I am not charging when I am using inverter load. I charge when I am RV sites with 30 A outlets or when visiting relatives with only 15 A outlets. I use the inverter when boondocking, ie when off the grid with no external power supply - like at a Walmart parking lot or a park with no...

I agree - the AIMS charges at 18A. As Signature Solar recommended the charger be disconnected from making contact with the EG4 battery after each charge, I wanted to know if any sort of DC circuit breaker would work. As for using an AC outlet to charge the EG4 Lifepower, I kept tripping my home...

I use a 2 space Square D Homeline 70 amp for my AC out and I could get another for the single AC line in as I do not wire the setup directly to the grid - I only plug in to charge the Lifepower battery. i want to leave my AIMS DC 48V charger connected to the 48V Lifepower battery so could I...

I will check for discharge - the charger I use is a AIMS Power CON120AC3648VDC AC Converter & Battery Smart Charger

Thank you, Sorcerer…I used a very good 30 A RV cord, cut it in half and use it with a surge protector when plugged into 30 A outlets at RV parks. Signature Solar say they don’t recommend directly wiring a plug to the AC input on the inverter. Regarding the second issue, if the DC battery...

Set up EG4 6500 inverter on a cart with 48V Lifepower battery to use for powering my RV off grid. I had wired a 30A RV style plug for direct AC input - when I called Signature Solar, tech recommended I not directly wire the plug to the AC in on the inverter and instead put an intervening breaker...

Started with Renogy Rover40A controller. PV array four 100w panels in series-parallel with calculated Imp 9.8A Vmp 40.8V, well under load specs for the Rover 40A. After 6 weeks the unit melted down, the display failed, the PV wires on a 20 foot run were very hot. I shut down the system, removed...

Mine uses 45 kWh a day in winter and 80 kWh a day in the hot Summer.

Thanks. The entire setup with the 4kw water heater, swim current motor is already part of the Endless Pool purchased package.

I am getting installation of an Endless Pool - I am in Phoenix, AZ. Energy need estimate from the company: 1. Water Quality System - 1.0 hp circulation pump and 4kW electric heater. Assume the filtration cycles are going for 6 hrs/day and heating for 4 hrs/day (of those six): 1.0 hp circulation...

I am connecting the EG4 LifePower battery to the EG4 6500 watt inverter/charger, so I plan to wire a 30 amp RV plug to the inverter AC input - should be OK, do you think?

Since the EG4 48V 18A battery charger is out of stock….does anyone have a suggested substitute or alternative charger?
