Not Sure This Is The Right System?
Request a Free Solar ProposalGoing off-grid on a property with a well means you need 240V, and that's the line most entry kits can't cross. This is the cheapest kit we sell that can: built for a small off-grid home, a shop running 240V tools, or a cabin on a well where the pump has to work without firing up a generator. A 6,500W split-phase inverter with 13,000VA of surge for motor starting, six 370W panels, and your choice of 5.12kWh or 10.24kWh of LiFePO4 behind it. That's about three hours of continuous well pump on the smaller bank and seven on the larger, and a pump runs in minutes, not hours.
The array is the small part of this kit. 2,220W of panels against a 6,500W inverter means the solar is sized for essentials, not for running 240V equipment off the sun all day. Think of this as the entry point into split phase rather than a kit built for heavy 240V loads every day. The inverter accepts up to 10,000W of PV, roughly four times what ships in the box, so plan on adding panels if a well pump or air conditioning is a daily load rather than an occasional one.

Three common load profiles, with how long each battery configuration carries them from a full charge and no sun. If you recognize yourself in the essential row, either configuration works and the smaller one is enough. Household and heavy profiles want the 10.24kWh.
| Setup | Continuous draw | 5.12kWh runs for | 10.24kWh runs for |
| Essential. Refrigerator, LED lighting, Starlink or router, phone and laptop charging, a TV. | ~500W | ~8 hours | ~17 hours |
| Household. All of the above plus a chest freezer, ceiling fans, a home office, microwave and power tool bursts. | ~1,500W | ~2 hours | ~5 hours |
| Heavy. All of the above plus a well pump, a window AC unit, or shop equipment running at the same time. | ~3,500W | ~1 hour | ~2 hours |
Same inverter, same panels, same everything else. The only difference is how much reserve you carry, which decides how long you can go without sun and how long 240V equipment can run. If you're unsure, the larger bank is usually the safer choice, and it's the harder upgrade to make later: added batteries work best when they match the originals in age and state of health.
| Configuration | What changes | Take this if |
| SGM-655M. 1 x 5.12kWh wall mount | One SG48100M battery at roughly 95 lbs, about 4.3kWh delivered to AC loads. Mounts on a wall and keeps the floor clear. | 240V equipment runs occasionally. A weekend cabin, a backup system, or a build where the pump is not a daily event. |
| SGM-6510M. 2 x 5.12kWh wall mount | Two batteries, roughly 190 lbs across the pair, about 8.7kWh delivered. Doubles the reserve and roughly doubles how long 240V loads can run. | Full-time off-grid living, a well pump running daily, or a site that sees several cloudy days in a row. |
The 2.22kW array produces roughly 9 to 11kWh per day at 4 to 5 peak sun hours.
Estimated runtimes below are from a full charge with no solar input, based on 4.3kWh delivered to AC loads on the 5.12kWh bank and 8.7kWh on the 10.24kWh bank. Real numbers depend on your specific appliances and how many run at once.
| Load | Draw | 5.12kWh runs for | 10.24kWh runs for |
| Chest freezer | ~100W avg | ~43 hours | ~87 hours |
| Refrigerator | ~150W avg | ~28 hours | ~58 hours |
| Cabin essentials | ~250W avg | ~17 hours | ~34 hours |
| Lights, electronics, internet | ~300W | ~14 hours | ~29 hours |
| Full household (essentials only) | ~800W avg | ~5 hours | ~10 hours |
| Window AC unit | ~900W | ~4 hours | ~9 hours |
| Microwave | 1,000W | ~4 hours cumulative | ~8 hours cumulative |
| Power tools (intermittent) | ~1,200W | ~3 hours | ~7 hours |
| Well pump (1HP) | ~1,200W running | ~3 hours | ~7 hours |
| Central AC (2-ton) | ~3,000W | ~1 hour | ~2 hours |
| Electric water heater | ~4,500W | under 1 hour | ~1 hour |
Read the bottom three rows honestly. This kit will start and run a well pump, a 2-ton central AC, or an electric water heater, which is the entire point of split phase. What it won't do is run them for long on the array that ships in the box. A well pump is fine, because it runs in short bursts. Daily air conditioning or electric water heating needs more system than this: more panels to generate it, and more storage to carry it after dark.

True split phase at an entry price - 120V and 240V from one unit, with no transformer and no second inverter. This is the cheapest point in our range where 240V equipment works at all.
13,000VA peak for motor starting - Pumps, compressors and welders draw far more starting than running. Double the continuous rating on tap is what gets them turning.
Room for roughly four times the array - Two independent MPPT trackers accept 5,000W each. The kit ships 2,220W, so the panels can grow for years before the inverter is the limit.
Charges from solar and a generator at once - Up to 140A combined, with 80A of that available from generator or shore power. A cloudy week doesn't leave you stranded.
Six units in parallel - Up to 39,000W of output if the site outgrows one inverter, without replacing what you already bought.
7,000+ cycle batteries - Rated past 7,000 cycles with an integrated BMS on each unit, protecting against overcharge, deep discharge and short circuit.

Every major system component, matched and ready to wire together. Battery count depends on the configuration you choose.

How it ships. Kits ship freight on a pallet, which runs longer than the parcel deliveries in our shipping policy: typically 5 to 10 business days. Liftgate and pallet jack are included at no charge, so the driver gets it off the truck and onto the ground at your address. The heaviest single piece is a battery at roughly 95 lbs. We send tracking as soon as it leaves the warehouse, and the freight carrier will contact you directly to schedule a delivery window. Someone needs to be there to receive it. Inspect the shipment before you sign. Damaged in transit? We cover it.
Installation. Because this is an off-grid system with no utility interconnection, permitting is often simpler than grid-tied solar. Requirements still vary by location, especially for roof-mounted arrays or permanent electrical work, so check with your local building department before installing. Plenty of our customers install these themselves. You'll want real electrical experience before wiring a 48V battery bank and 240V circuits.
Wire all six panels as a single series string on one MPPT tracker. This matters more on this kit than on most. The SPH6548P's trackers don't start working until 150VDC, and six of these panels in series sit at roughly 241V, comfortably inside the 150 to 450V window. Splitting them three and three across the two trackers puts each string near 120V, below the floor, and the inverter simply won't harvest from them. Leave the second tracker empty until you add panels: any future string needs at least four of these panels to clear 150V.
The jump to 6.5kW is about capability, not size. If anything on your property is 240V, this is the band to start in no matter how much storage you need.
| Kit | What changes | Who it's for |
| SGR-5KE. 5kW, 2.7kW solar, 10.24kWh, 120V | No 240V at all, but more array and more storage for the money. | Cabins, tiny homes and workshops with nothing but 120V loads. |
| This kit. 6.5kW, 2.22kW solar, 5.12 to 10.24kWh, 120/240V | The cheapest point where 240V equipment works. The array is deliberately modest. | Wells, shops and small off-grid homes where 240V is needed but not constant. |
| SGR-8K10E. 8kW, 3.6kW solar, 10.24kWh, 120/240V | 16,000W surge instead of 13,000VA, half again the array, and 10.24kWh as standard. | Full-time off-grid houses running 240V daily with confident motor starting. |
Before you order, it's worth a short call. Our sales engineers will size the kit against your actual loads, tell you honestly whether 2,220W of panels is enough for how you plan to use the 240V side, help you pick between the two battery configurations, and put together the list of site-specific parts your install will need.

Does this kit include everything I need to install it?
It includes the major system components: the inverter, your chosen battery or batteries, all six panels, the DC and PV breakers, solar extension cables, the inverter cable, Z-brackets, and the manuals. What varies is the mounting and building side of the job, and that's site by site. Depending on your site that typically means wall mounting hardware rated for your construction, interconnect and communication cables if you take the two-battery configuration, rail racking if you're mounting on a shingle roof or the ground, conduit, junction boxes, building wire, a critical loads panel or transfer switch, generator or shore power input wiring, and labor. Those depend on your structure and your local code, which is why we spec them per site rather than boxing a set that might not fit. Tell us about your install and we'll list exactly what yours needs.
Which battery configuration should I buy?
If 240V equipment runs occasionally, 5.12kWh is enough. If you live off-grid full time, run a well pump daily, or get long stretches of cloud, buy the 10.24kWh. It's also the harder upgrade to make later, because added batteries work best when they match the originals in age and state of health.
Can this run my well pump?
Yes. A 1HP pump draws roughly 1,200W running, and 13,000VA of peak capacity covers the startup surge. On the smaller bank that's about 3 hours of continuous running, which is far more than a pump actually runs in a day.
Can it run central AC?
It will start and run a 2-ton unit, but not for long on the included array. Expect about 1 hour on the small bank and 2 hours on the large one from storage alone. If air conditioning is a daily need, add panels and storage, or step up to the 8kW kit.
How should the panels be wired?
All six in one series string, on one of the two MPPT trackers. The trackers need 150VDC before they start working, and six of these panels in series sit near 241V. Three and three across both trackers lands each string near 120V, below the floor, and neither tracker will harvest. Any string you add later needs at least four of these panels for the same reason.
How much energy will this generate daily?
The 2.22kW array produces roughly 9 to 11kWh per day at 4 to 5 peak sun hours. Actual output depends on your location, season, panel angle, and shading.
Can I add panels or batteries later?
Yes, and on this kit adding panels is worth planning for. The inverter takes 10,000W against the 2,220W included. If you buy the single-battery configuration you can add a matching SG48100M later, and matching them closely in age and state of health gives the best result.
Can I install this myself?
Many customers do. The line worth drawing is where the system meets your building: setting the inverter, running PV, and wiring the battery bank are within reach for someone with real electrical experience, while tying into an existing house panel is work for a licensed electrician.
Is LiFePO4 safe?
It's the safest widely available lithium chemistry, with strong thermal stability, long service life, and minimal maintenance. Every battery includes BMS protection.

Buying solar online should not mean guessing your way through the install. Here’s what you get with Off-Grid Source.
Wow, so much power I’ve exceeded my goal already and I’m gonna tie in more
The whole process was super fast and accurate
Really well made, comes with all the cables and everything that you would need for initial setup. Looks simple to set up. Well worth the cost for the size of the solar panels as well.
Nice small kit! Looks good
We only received 2 out of 3 pallets of parts for the kit. Had to call multiple times over the course of a week to get the rest my parts and still haven’t even received a callback with an update as to when we can expect these parts.
so Im about to go off grid I called Manny walked me through everything so I could truly understand what i needed and never tried to upsell me he was honest and made a customer for life
