About EG4
There are 22 EG4 products in the SolarBazaar catalogue, the largest share of them batteries. The listings are structured the same way for every manufacturer, which makes side-by-side comparison across brands straightforward.
The catalogue breaks down into 3 categories — 13 batteries, 8 inverters and 1 charge controllers. Batteries are where the brand is deepest, with 13 of the 22 listings.
Listed EG4 prices run from $ 450 to $ 9,945 (USD), which reflects the spread between the brand's entry-level units and its largest or most feature-complete models. Prices are indicative and move with supply, import duties and exchange rates — use them to compare brands, not as a quotation.
Understanding Batteries
A solar battery stores the energy your panels generate during the day so it can be used after sunset, during a power cut, or whenever grid electricity is most expensive.
Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.
- continuous charge and discharge current, which limits how much power you can draw from the pack
- cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4
- round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid
- communication protocol (CAN or RS485) for talking to the inverter
- nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh)
Choosing the right battery for your system
The guidance below applies to any battery, EG4's included. Work through it against the specifications listed on this page before you compare prices — a cheaper unit that does not fit your voltages, currents or protocols costs more in the end.
- Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.
- Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.
- Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.
- Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.
- Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.
What buyers get wrong
- Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.
- Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.
- Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
Buying EG4 in Saudi Arabia
Product availability on SolarBazaar is scoped by country, so this page shows the EG4 range listed for Saudi Arabia plus any items published globally. Switching country in the header changes both the catalogue and the currency prices are quoted in.
SolarBazaar is a comparison directory rather than a shop: we publish specifications, prices and documentation so you can shortlist equipment, then buy from a local distributor or installer. That matters for warranty — cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports EG4 in Saudi Arabia before ordering.
If you are still shortlisting, Anker, BigBattery, Dakota Lithium and Discover are listed in the same category and can be compared against EG4 spec by spec.
EG4 — frequently asked questions
How many EG4 products are listed on SolarBazaar?
22 products, spread across 3 categories: 13 batteries, 8 inverters and 1 charge controllers. The count reflects what is listed for the country you are browsing, so it changes if you switch country.
What does EG4 make?
EG4's listed range is led by batteries (13 of 22 listings), followed by inverters (8) and charge controllers (1). A solar battery stores the energy your panels generate during the day so it can be used after sunset, during a power cut, or whenever grid electricity is most expensive.
How much do EG4 products cost?
Listed EG4 products run from $ 450 to $ 9,945 (USD), depending on capacity and model. Prices are indicative and change with supply, duties and exchange rates, so treat them as a comparison reference rather than a quotation.
Is EG4 a good brand?
SolarBazaar does not rank manufacturers editorially — we publish the specifications so you can judge them against your own requirements. For EG4, the practical checks are the communication protocol (CAN or RS485) for talking to the inverter, nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh) and usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%, and whether the warranty is serviceable in Saudi Arabia. A brand with strong specifications and no local support presence is often the more expensive choice over a system's life.
Where can I buy EG4 products in Saudi Arabia?
SolarBazaar lists and compares equipment rather than selling it. Use the specifications and prices here to shortlist, then buy through an authorised distributor or installer in Saudi Arabia — that route keeps the manufacturer's warranty intact, which direct grey-market imports usually do not.
